To me it seems like the road system and crosswalks can't be changed for the most part. So education and awareness is the only choice we have for ourselves and children. I guess in a way doing a background check on a babysitter is kind of like the DMV testing and doing checkup on drivers to make sure they are capable of driving, though, it's debatable that they are doing a good job. I could be wrong, but I'm guessing that most auto/pedestrian collisions are at intersections and for the most part they cannot be changed. The automobile is here to stay I think unless public transportation is revolutionaized somehow or we somehow centralize a lot of things so people don't need highspeed trans. to get there. I think education is the answer to most of the worlds problems myself. Knowing is half the battle right?
