On a similar note, what happened to cars that would lock you out of interacting with the infotainment system whenever you were driving faster than parking lot speeds? I assume this was some regulatory/safety requirement.

I remember cars used to either implement that feature, or outright prevented you from even pairing a new Bluetooth device when your car was in Drive. But then all of a sudden it seemed like automotive companies stopped and touchscreens became acceptable. Does anyone know what changed?
