Maybe they should institute the emergency foam filling system to protect the occupants as well

Excellent idea. You inspire joy joy feelings in those around you.

maybe instead of adding even more complexity to solve the issues our solutions are creating, we could wait until we have solutions that don't create huge issues. What happens if the thing locks all the doors and manual controls and then drives off a bridge? Or if it's caught fire. Personally I'm barely okay with taking planes, if there was a car that could, at any moment, turn into a prison cell I'm not going near one of those things as long as I live. Even if they say they've disabled the "feature". Do we really trust these corporations with our lives so much that we're willing to get perma-locked into their test vehicles?
