Whether I'm walking or driving, I find myself always looking to my upper left to see who is behind me. However, when I'm walking or driving, I'm not wearing my bike helmet with rear view mirror attached, so I can't see who is behind me. I actually have to turn my head to do that when walking or look to my lower left/upper right for the rear view mirrors in the car. I've come to depend far too heavily on my rear view mirror.

I'm much more nervous about driving now that I'm in my car so little.

Much, much rather be on my bike.
