It increases the costs of repair. Everything need to be calibrated.Until the 2027 model year, we should have the option to turn off the annoying nanny. Just like we should have the option to turn off all the other annoying nannies.
You know what's dangerous and distracting? A car that is constantly flashing lights and sending messages across it's screens. Each one causing you to divert your eyes from the road for a moment. I wonder how many accidents are caused by the distractions of the very devices that are supposed to make us safer? It's a valid question. Pretty soon it's going to flash us a warning then warn us that we're distracted.
It's also a cost consideration. All these federal requirements "to make cars safer" (technology for the sake of tech? Lining the pockets of parts suppliers?) do indeed come at a cost. Our cars are more expensive and complex. The average new car runs close to 10x more lines of code than a Boeing 787 Dreamliner. Seriously, some cars run 100 million lines of code. Cars are so complex and parts intensive now that about 25% of them are written off as a total loss by the insurance companies (in the US) after a crash.
