Due to federal regulations, side pillars must cover passengers' heads, with the result the pillars are quite wide and limit visibility. In other words, the regulation of attempting to save lives ironically results in not saving lives.
About a year ago I dorked a young scooter rider who cursed at me. I simply stopped, and said, "I apologize, I did not see you when I should have." He was rather taken aback but it was about then I greatly reduced my driving to near zero (drove four times in the past two months).
I've simply had it with our car centric culture, it's ridiculous to put such dangerous things in the hands of such inattentive overly emotional creatures such as us, where the penalty is so severe usually born by people least able to defend themselves (in my case the young poor kid on the scooter).
Not that I'm particularly concerned with the well-being of others; it's just that shoving it to a kid like that is an affront to my sense of fair play.
