Our most recent car is pretty much keyless. No big deal there, but it also has a feature that makes it all but inpossible to lock your keys in the trunk. It can tell where the keys are.
In 10-20 years I expect we could have something doing a forced shutoff or police notification when a phone is being used in the drivers seat and the vehicle is in motion.
Or we could go in ht eother direction and have the stupidity of replaceing buttons with touch screens that some car companies are pushing.
