Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.

GM recalls 740,000 vehicles over daytime running light issue

General Motors is recalling over 740,000 vehicles due to a daytime running light issue that causes all of the affected cars to run afoul of Federal Motor Vehicle Safety Standards. Vehicles affected by this recall are spread across many of GM’s brands. Models include the 2020-2023 Cadillac CT4 and CT5, 2021-2023 Buick Envision, 2022-2023 Cadillac Escalade and Escalade ESV, 2022-2023 Chevrolet Silverado 1500, Suburban, Tahoe and 2022-2023 GMC Sierra 1500, Yukon, and Yukon XL. GM says that the daytime running lights may remain on in these cars when the headlights are activated. This is a problem, because FMVSS rules require that the daytime running lights deactivate once the headlights turn on. If the DRLs remain on, GM says that could result in additional glare, thereby increasing the risk of an accident. The cause of this failure to deactivate the DRLs comes from body control module software that “under a combination of certain pre-conditions, could fail to deactivate the DRLs,” according to GM. Other GM vehicles were tested, but due to a difference in software or hardware, they remain unaffected. If this is reminding you of another recent GM recall, youÂ’d be right, as GM recalled another 340,000 vehicles for the same issue last month. After that original issue was found within GM, the company began looking into its other cars to determine if the population was larger than originally thought. GM found the additional vehicles included in todayÂ’s recall have the problem. The fix will either be via an over-the-air update or it will require you to bring the vehicle into a dealer for a software update, depending on which vehicle you have. Owner notification letters letting folks know what is necessary are currently scheduled to go out on January 23, 2023. Related video: Cadillac Escalade Infotainment Review

Roll pins in recalled 2014-2015 Cadillac CTS V-Sports could crack

General Motors has issued a recall for select 2014-2015 Cadillac CTS V-Sport sedans due to roll pins in the rear differential that could crack. The recall only affects 2,866 vehicles, but it is expected that 100% of those vehicles have the defective parts. According to NHTSA Campaign No. 20V038000, 2014-2015 CTS V-Sports built between July 1, 2013 and May 15, 2015 have roll pins in the rear-axle differential that could "fatigue" and "fracture." If these pins were to break while the vehicle is in motion, it could cause the rear to lock up, which might create a potentially dangerous driving situation. In September 2019, a GM engineer noticed a forum discussion about the problem with the V-Sports, which can be easily identified by their twin-turbo 3.6-liter V6 engines. Because he had dealt with similar issues with his own personal vehicle, he submitted a report, and an investigation was opened the next month. To make good with its customers, GM has promised to replace the rear differentials on all affected vehicles. The recall report says the roll pins in the replacement parts will have "increased strength" and a double-shear design rather than the original single-shear design.  GM plans to send customers recall identification notices starting March 9, 2020.
