But phone use is a symptom, not a cause, of people not feeling they need to take any responsibility while they're behind the wheel. As I've said many times before, running has been a revelation to me, because I get to face traffic and watch what drivers do, and most of the 20% or so who target fixate on me are NOT on their phones.

As much as I was uncomfortable with MADD's tactics at the time, they were plainly effective in changing the culture around drunk driving. I think a similar effort is what's called for here. Court-packing, prosecutor-harassing, letter-writing, the whole business, and for victims of ALL negligent drivers, not just the ones who happened to be extra vulnerable before the driver hit them. And making vehicular homicide a strict liability offense just like every other traffic offense.
