friend of mine in late 70's has resorted to Tesla's driverless functions. personally i would never resort to that option, although most modern vehicles have numerous safety features that can help with age impaired drivers in vehicle operation, which is a good thing. but no, i'll be in charge of driving
having said that, modern vehicles are packed with creature comforts, power, and distracting electronic gadgetry that imho only isolates drivers from from the reality of the road. add age, & it's a recipe for trouble.
in the OP's case, good to hear everything worked out, no one was hurt, and a thumb's up to the OP for sharing his experience in this forum. regards
