I commute to work 75 miles round-trip every weekday. Two or three times a week I encounter people doing ten miles under the speed limit, and when I pass them they invariably are holding a digital device in front of their faces with one hand and the steering wheel with the others. Now they’ll be looking at their dashboards instead.
On one trip from Stockton to San Francisco, I saw a fellow with a laptop propped up on the dashboard behind his steering wheel. . . watching a movie. . . porn. He had NO HANDS on the steering wheel at all, doing 75 MPH. I could not see how he could see ahead at all.
On the way home, we spotted another one with the laptop propped on the steering wheel. . . he was typing away with both hands. I was wondering what he was steering with! Where are the California Highway Patrol when you want them to be around?
On the other hand, I have seen numerous women driving full speed on the road putting on their make-up, using the rearview mirror, holding an eye open with one hand and brushing mascara on with the other, also at 70 MPH. That's called "farding" while driving. . . and Rush Limbaugh had a campaign against it back in the early '90s which people though he was saying "farting!"
It is not the device, or even the act, it is the idiot behind it.
CarPlay is built in and is voice activated — with no reason to remove your hands from the wheel or eyes from the road to do anything with it.
