Motormouth: Cars can ‘read,' but sometimes not very well
P.H., Edina, Minnesota
A: Yeah, some vehicles mistake route numbers for speed limit numbers. Like me, they may be a bit numerically dyslexic. Or, perhaps, a remedial reading class is in order. Thanks for the chuckle.
Q: I recently took my 2018 Buick Encore with 44,000 miles in for an oil change at an all-purpose auto repair facility. The service manager advised (and showed me) that my coolant level had dropped about 2 inches below the fill indicator line on the reservoir, and that as a result, I should get a complete cooling system flush. He explained that there might be acidity in the coolant, which could ultimately corrode internal engine parts. My owner's manual recommended this service at 100,000 miles.
D.B., Winfield, Illinois
A: I would top off the coolant with some premixed stuff. Then I would check the coolant reservoir regularly. The level is usually higher after running the engine due to expansion. The next morning, it will be lower as the coolant is sucked back into the cold engine. If you keep adding coolant, have the cooling system checked out. The service manager is right that worn out coolant can lead to internal engine problems, especially the water pump.
Q: I bought a 2024 Ford Maverick hybrid truck in July 2024. It has 3,000 miles on it so far and I was wondering when it should have its first oil change. Since the engine is running on the battery part time, how do you figure the miles it has actually driven in a year? The owner's manual doesn't say anything about it. I hope you can answer me on this.
R.D., Yorkville, Illinois
A: It is often hard to give up control and allow the vehicle's oil life monitor to let you know when it's time to change the oil. But that is what you should do.
Q: I own a 2021 BMW 430xi. It has almost 8,000 miles on it. Several months ago, the warning sign came up and it indicated my oil needs to be changed. My husband insists it does not. I had it changed about two years ago, before the warranty expired. When I contacted the dealer about it, they said the oil is "old" so, yes, it needs to be changed. My husband insists it does not. Of course, the warning sign appears every time I drive, which annoys me and worries me that I am causing harm to the engine due to my husband's stubbornness. Who is right here?
D.I., Dyer, Indiana
A: BMW uses a condition-based service system; it monitors the condition of the oil. The CBS system tracks your oil's life based on mileage, the amount of fuel consumed and an oil quality sensor in the oil pan. Trust it when it tells you to change the oil.
Q: I have a 2018 Subaru Outback with 112,000 miles on it. I take very good care of this car and faithfully follow the manufacturer's maintenance recommendations. The dealer tells me that I need to replace the timing chain at 120,000 miles. Other sources inform me that I never need to replace the timing chain. What's your thought about this?
C.H., Cologne, Minnesota
A: The timing chains on the FB25 engines are maintenance-free.

S.F. residents had parked in their driveways for years. Then someone started snitching
For decades, Larry Reed and his neighbors had squeezed their cars into tight, sloping driveways in San Francisco's Dolores Heights neighborhood. Often the tail ends of the vehicles would extend to the sidewalk. Nobody ever protested, Reed said. Until about six months ago, when the first complaint rolled in. 'This has never happened in years past,' Reed said, recalling how a somewhat apologetic parking control officer rolled up one day, to assess a report that someone on the unit block of Chattanooga Street had parked a car over the property line. After leaving a warning notice for the culprit, the officer swept the block for other violators, including Reed's gray electric BMW. 'I really try to keep my car so that the space is pretty accessible,' Reed said, noting that he always has parked the same way, flush with the garage door. Inevitably, the back wheels and bumper stick out. California law forbids parked vehicles from blocking even small portions of public sidewalks, ensuring safe passage for wheelchairs, strollers, seniors with canes and people on crutches, among others. On Chattanooga Street, anyone who flouted the rule got a warning, at minimum. But as driveway parking enforcement ramped up throughout the city, frustrated residents pushed back. Some believed the San Francisco Municipal Transportation Agency was unfairly cracking down on infractions that didn't really create a safety hazard. Others suspected that a persnickety neighbor might be snitching on them — and in some cases, manipulating the photos attached to the reports. Sharon Gillenwater has avoided war metaphors when discussing the three citations her family has received for parking in the driveway of their Noe Valley home, worth a total of $324. Technically, the tickets were just, Gillenwater said, conceding that her Volkswagen SUV and her son's Subaru wagon exceed the length of her front stairwell. Still, Gillenwater can't hide her exasperation over what she describes as overzealous punishment. 'We're not fighting the law, we all agree that strollers and disabled people need to pass,' she said. 'But can we just be in the spirit of the law? In our case, there is plenty of room for two wheelchairs to go in tandem down the street.' At the same time, she and other Noe Valley residents wonder whether someone is trolling them, filing complaint after complaint about driveway parking to demand a response from the SFMTA. Gillenwater has observed that many complaints have text captions with identical font, and some use old photos as evidence. In one case, a resident drew two reports when she and her car were hundreds of miles away in the Sierra. In another example, someone filed a complaint against Gillenwater's son when his Subaru hadn't been in the driveway for two days. 'It's kind of our neighborhood murder mystery,' said Gillenwater's husband, Andrew Keeler, relaying what has become a tense joke. Searching for clues, some neighbors discovered an app called Solve SF, which uses artificial intelligence to ease the process of filing reports through the city's 311 complaint system. This concept incited suspicion in Noe Valley, where residents typed up five pages of oppositional research on Solve SF, mainly to uncover why the volume of illegal parking complaints in Noe Valley suddenly spiked in June. They blamed the app for wasting 'valuable city resources' (because some complaints don't result in tickets) and said it promotes 'questionable use of gamification of reporting.' 'So someone wrote this whole thing about my app, huh?' said Patrick McCabe, developer of Solve SF, who is proud of his innovation and its impact. However, he shot down a popular theory in Noe Valley that his app is, in effect, a troll enabler. According to McCabe's own analysis, a small portion of 311 complaints in Noe Valley last month used Solve SF, and the app wasn't responsible for the 'doctored' 311 reports that keep recycling old photos. McCabe is familiar with those reports, and has his own idea of who generates them: someone who snaps photos of illegally parked cars in driveways, stores them in a cellphone and keeps a text overlay for each one with the violator's address and license plate number. In all likelihood, McCabe said, the mystery snitch uses these stored photos to refile the same complaints, predicting that people will continue parking in driveways in which their cars don't fit. 'I see this (type of report) daily,' McCabe said. 'And they should use my app. It would be easier.' Meanwhile officials at the SFMTA said they will continue responding to complaints about illegal parking, and issue tickets when warranted. Last April, the SFMTA began a ' focused parking enforcement plan ' to enhance safety on sidewalks, targeting each of the city's 11 supervisor districts on a rotating basis. Officials said they would prioritize specific violations, including parking on the sidewalk. Supervisor Rafael Mandelman has fielded several emails from constituents in Noe Valley and the Castro who feel they've been unfairly cited 'for something they've been doing forever.' He can sense their agony, while also viewing the citations as artifacts of good governance. 'To the defense of the SFMTA, it's not like this law doesn't make any sense,' Mandelman said, explaining that public sidewalks should not be overtaken by private parking. Furthermore, he said, it's only fair that parking control officers treat everyone equally. They can't make exceptions for people who feel they're only obstructing a small portion of the sidewalk. And if they respond to one complaint, it behooves them to ticket everyone on the block who is committing the same infraction. 'It's really hard to ask these officers to be platonic guardians, and decide whether they should enforce in each individual case,' Mandelman said. 'They're not really supposed to be exercising discretion.' Cristina Rubke, a former SFMTA board director who uses a wheelchair, adopted a similarly diplomatic perspective. She expressed empathy for drivers struggling to cram their vehicles in snug spaces of San Francisco, including their own driveways. But, on balance, she's happy that the agency is enforcing the law. 'Honestly, most people are good actors,' Rubke said, 'they're not trying to force a person in a wheelchair out into the street. And yet as a general matter, these citations exist as a reminder that (other) people need to use that space.' Rubke remembers many instances when she has had to cross a street to avoid a car jutting onto the sidewalk. A couple of times she has tried to maneuver around the overhang, only to hit a crack in the pavement, and then backtrack. Reed said he's happy to rush out and move his car for any passerby, though he would prefer they call or ring his doorbell, rather than filing a complaint. To encourage civility, he posted a sign at his front steps. 'If you ever have a concern about our vehicle, please reach out,' the sign says, providing his phone number. 'We're happy to move it.' Since posting the sign, Reed said he hasn't received any more warnings. Which hasn't exactly solved the problem: His BMW still doesn't quite fit in the driveway.

Has Bentley Officially Surpassed Rolls-Royce?
Rolls-Royce and Bentley are tied to each other forever. As recently as the late 90s, the two automakers made vehicles that were virtually indistinguishable from one another. Each had its trademarks, badging, and in Rolls-Royce's case, the Spirit of Ecstasy and grille design. Fast-forwarding three decades, we find two brands with distinct personalities and heritage. Looking closer, we see two brands that have set out to accomplish similar things - and achieved on very different levels. But first, a quick history lesson. Bentley Motors began life in January 1919 as World War I ended, debuting its first car later that year. The company delivered its first car in the following year and won the 24 Hours of Le Mans in 1927. Then, the brand repeated its wins in the three years following. Rolls-Royce bought the brand when it went into receivership on the heels of the Great Depression. The newly acquired now-subsidiary's first car was a Bentley 3.5-liter that appeared in 1933, powered by a Rolls-Royce engine. The latter part would prove to be a trend as all Bentley models produced after the merger until 2004 relied on Rolls-Royce engines and chassis. After changing hands in the 1970s, Rolls-Royce (including Bentley) went up for sale in the late 1990s. BMW and Volkswagen were poised to become the inheritors of the luxury crown. BMW was already providing powertrains for Rolls, and took further steps to purchase the name and logo for Rolls-Royce. For a sizable $703 million, Volkswagen purchased the designs, nameplates, and the facilities themselves. But, without the rights to the name and badging, a compromise needed to be met. Thus, VW took Bentley, and BMW got Rolls-Royce. Effective January 2003, the two brands were finally separate entities. After twenty-two years apart, how have they fared? Let's start with Rolls-Royce. The original nameplate has carried itself well into the 21st century, and 2024 saw the brand deliver 5,712 cars, its third-best recorded. Here, Bentley compares favorably. The Crewe-based automaker delivered nearly double the number of cars as Rolls, with 10,600 cars finding new homes. However, volume is only part of where these brands generate their revenue. Both place a heavy emphasis on customizability; Rolls-Royce has Bespoke, while Bentley offers Mulliner. Last year, Bentley saw revenue per car rise 10%, and a lot of that comes from the fact that 70% of the cars delivered had at least one Mulliner inclusion. Rolls-Royce says, similarly, that it saw a 10% increase in Bespoke content overall, enough to set a record for the brand. Bentley trounces Goodwood in volume, and profit is a similar story. Bentley reported a profit of $439 million. Meanwhile, BMW reported that Rolls-Royce generated around $140 million in profit, demonstrating that the brand is also very likely making less, percentage-wise, per car than the boys in Crewe. The story remains consistent no matter which arena you pick. Rolls-Royce, overall, accounts for roughly 1% of parent company BMW's profit. Bentley? Last year, despite a downturn in profits, the brand accounted for around 2% of Volkswagen's profit. We've established that Bentley is making more money than Rolls-Royce, but what does the future hold? Bentley certainly isn't resting on its laurels, just recently announcing three new stores for North America in desirable locations - Santa Barbara, California, San Antonio, Texas, and Oakville, Canada, a Toronto suburb. An exec was recently quoted as saying there's "no real limitation" on what the automaker can or would build you, even offering a pickup truck. Finally, Bentley also laid the ground for a new BEV assembly line back in March 2025. Then, in July, Bentley opened up a brand-new design studio converted from one of its oldest and most heritage-filled buildings. BMW isn't putting Rolls-Royce out to pasture yet, though. Last year, the brand added two new Private Office locations and an invite-only network for Rolls-Royce customers to configure their vehicles. Furthermore, the brand committed around $400 million to expanding manufacturing at the Goodwood facility. The numbers don't lie. It's a fairly accurate statement to say that Bentley has surpassed Rolls-Royce, at least for the time being. However, even after a century, both brands are still growing. Notably, the big B doesn't have a single all-electric model. Meanwhile, Rolls-Royce has cleaned up with the Spectre, simultaneously attracting a whole new kind of buyer and moving units. It's too early to tell which of these historic luxury brands is going to come out on top, but Bentley has certainly taken the lead, and is obviously working and spending hard to maintain it.
