Saw a local news segment today. There has been a rumor that buried deep in Biden's infrastructure bill, it is written that manufacturers have to put in a kill switch on all new cars. Well. they did some digging and there is nothing about a "kill switch". (I could get behind that considering how many pursuits end badly) But, it is written that manufacturers will be installing devices to prevent impaired driving. There was no elaboration or additional details. Not that I would have any issue with this either, but I really don't see intoxilocks being installed on every car. Rich folk wouldn't stand for their Escalades telling them they could start the motor 'cuz they're drunk.
As previously mentioned, the increased electronics and internet connectivity will make this easily enacted. Even OnStar 20 years ago was able to receive signals from the car, send signals to the car for unlocks and diagnostics. My son's '14 dart's back-up camera would stop working when his fuel light activated. He had to get to go to the dealer and physically get an update, just like an iPhone. Nowadays those updates are downloaded while driving down the road on newer cars.
Just wait 'till our vehicles get A.I., get an attitude and decide to not start or drive us over a cliff.
