What do you guys think of hands-free driving in the newer cars?

EVERY SINGLE system in cars fail at some point. That's all I'm sayin.
Right, and a coding error may not show up until a specific situation occurs, then every single person with that model/system will all experience an accident in that situation...every single one..then what??? Once realized every car is 'grounded' until a whole new re-flash with the fix is written?
No F'n thanks,...
