Re: Not for me
If you're in traffic there's no way to pull over because you're surrounded by other cars. And as for putting it on the windshield, traffic codes where I live forbid anything obstructing the windshield (including dangling air fresheners) apart from those built into the car (like the mirror), so that means the device must go under the dash. It can't block the speedometer because that's against the traffic code, too, so that basically puts it either in a console mount or on the passenger seat: both too tricky to reach when your eyes are on the road. BTW, it's right-hand traffic where I live, so my dominant hand is at the center, not at the window.
Look, I'm speaking from experience on this. I can at least say "OK Google, find nearest detour" while my eyes are on the road, and it's something quick enough that I don't get hypnotized.
