This is a good point. My first inclination is to applaud the increase in the penalties, but you're right, I have to imagine that killing someone is more of a deterrent than any amount of fine, so it probably doesn't matter how high it gets. Maybe a better option would be to drop the "causing death" angle from the legislation. In other words, make careless driving itself the focus, instead of just one of the subset of possible outcomes from careless driving. If people knew they could be fined $50,000.00 for texting while they drive, regardless of whether or not they hurt anyone, I'm guessing that would keep their eyes off their phones.
