There's only one group of people that have any excuse to be on a cellphone while driving. Doctors who are possibly giving instructions to personnel at a hospital or the like.

Of course the 2 doctors I know pull off to the side of the road if possible to make these calls so they can concentrate on what they're saying.

It can wait until you're off the road.

It's amazing. I think a lot of people under a certain age would have died 20 years ago. No cellphones or computers.
