Asking questions was obviously a joke.
As for the rest I don't know what would it take to make sure the driver is paying attention. Distracted driving is the most common cause of accidents so clearly even in normal cars we can't be sure drivers are paying attention. I think we can agree cruise control is generally good but I have no idea what happens once the car has line following. Is it the same? You focus on the road more? Or do you stop paying attention completely? I think it's a questions to scientists really. Someone has to test it rigorously before it's actually added to the cars. My feeling is that once you don't have to drive by yourself (as in turn and brake) you eventually stop paying attention, so yeah, either the car drives itself 100% or you drive.
I've been waiting for something with multilingual typing for years. I constantly switch between 3 languages and it's a PITA.
