That's what you think. As you pass through the underpass, the train derails and falls from the bridge onto you.

I never use a mirror. I used to watch the traffic in my car's rear view mirror and got really annoyed about all the crazy driver that were driving way to close to my bumper. Which in response made me do stupid things in order to get them aware that they are too close. It didn't help any and just endangered everybody even more. So I just ignore what's happening behind me and put the trust into others. Instead I focus on what's ahead of me. I mean what do you really do with a mirror on a bike? Watch people as they approach you and pray they won't hit you or stand on the shoulder and wave the cars as they go by? So at least for me I live a stress free healthier and better life without a mirror ... until I die one way or another.

Of course I know that I'll die while riding in town going to work. I'm rushed, car drivers are rushed, everybody drives/rides crisscross through town, ... On tours I'm much more peaceful, the roads are much quieter and nicer, and of course I don't meet as many vehicles.
