I think you're being pretty harsh. I don't have a death wish, I ride my bike frequently in SF because I love to ride, it's great exercise, it's by far the fastest way to get to work, and it's one less bicyclist-killing machine on the road. From a philosophical point of view, if everyone did what I did, there would be a lot of upsides for everyone. If everyone decided to ride a car, there would be many downsides.
