I have to grab hold of something with my hand, on the back of the screen, to steady my hand while the car is in motion, then I can use fingers to select the button on the screen.
overall, its NOT IDEAL for driving!
well, duh. we all knew this. the largest 'bigliest' elephant in the room - screens are not safe for cars since you HAVE TO take your eyes off the road to use them. there's no touch or tactile clues.
what I find really amazing is how tesla and the others got away with bribing the authorities to look the other way, when legislation was created that specifically addresses the distraction issue about drivers. in calif, you cant even mount anything to your windshield (lots of reasons). you can't play video games or have a live movie going while you drive. so why is it ok to have us constantly glance AWAY from the road to the screen just to operate the car?
using my phone gets me a ticket. why is using my tesla's screen ANY DIFFERENT? someone please answer that. I see zero diffs. mounting the phone and touching it gets you a ticket while you drive. and yet.....
tesla is on the border of legality and just barely, somehow. other vendors that play with screens like this, them too. the move away from real controls has hurt, not helped, distracted driver syndrome.
there's a lot I like about that display, but part of me would like to see it reeled back by more rational minds. I do think we've taken this too far and its just lazy to put all controls there. lazy for software and hardware designers. yeah, we ask them to make a decision and stick with it. and they just can't!
