For those of you who keep saying how much of a dumbass the people who supported this are, picture the following scenario:
You're driving along at 40-45 mph, when suddenly a pedestrian walks into the middle of the road right in front of you. There isn't enough time to stop before you reach him, so you swerve to the side... into oncoming traffic. Suddenly you and possibly the people in the car that hit you are injured or dead, because some dumbass pedestrian wasn't paying attention to where they were.
The law isn't just about protecting the idiots, it's about protecting the innocent people who encounter them.
