This is a suggestion to Tesla Motors. As a safety question, why haven't we seen larger buttons on the screen when dialing a new number? It is extremely dangerous to drive and dial. The numbers are simply too small! I often make the wrong number and have to start again. Very dangerous! As a safety protocol, please increase the size of the phone buttons to, say, 1 and a half inches square? I'm surprised no one else has asked for this much needed improvement. Thank you!
