Unfortunately, it's not just the big SUVs any more.

I've seen people riding motorcycles talking on the phone.

I ride with a guy who will sometimes take phone calls in a paceline (not a tight or extremely hard paceline, but still).

Part of it is "Mr. Important," certainly, but I think most of it is the culture that lets people believe that they don't need to pay attention when they're on the road. Honestly I see more women (and girls) than men and boys talking on the phone while driving.

I mean, just start the topic on this very forum of wearing an iPod while running or riding...
