"Simplified UI"? I think you mean the confusing UI that isn't the one I learned before I was trying to switch lanes on the freeway.

Some day, I hope a lawyer will team up with a UI researcher, and then sue car manufactures for "safety theater" features like this that endanger people.

One of my favorites? The click through legal disclaimer that blocks my view of the backup camera screen every single time I pull out of a spot in a parking lot.

A runner up is "we can't let the passenger type a destination into the navigation system because the vehicle is moving"
