Re: 20%
If it is more than a short drive, pulling over to answer a text or an email must also be a drag.
Even a couple of goes at voice control is worth the effort, especially where you can't stop legally or safely.
Or you could just drive one-handed with a giant, opaque phone against your head through a red light at a large interchange with loads of cars starting to cross like I saw yesterday.
Even worse than the Smart car (not the driver though) driving over the pedestrian crossing at the red light I was waiting at, crawled into the crossroads, looked left and right and drove across.
Red lights soon to be advisory only, yield, not even stop and yield, apparently. As indicators have already become sadly.
