Cars are dangerous, not only to those who use them, but to those with whom they come in contact with.
It's hard to count how many people I've lost to cars. I my self am user. I spend about 1.5 hours a day driving hither and yawn. It's is a potentially, very devastating habit. We all know some one who has been affected by cars, my sister has hit by one when she was kid. And Ive lost a few friends and family members to them over years as well.
I'm sorry GIT, my above logic is superlative. And worthy being reiterated.
