I have to keep my head down. It doesn’t matter most of the time because I ride a dedicated bike trail route. I also ride at the end of my day or even at night. I don’t want to know more than I need to about cars. My PTSD is too bad for traffic. I mostly only ride for physical therapy now. It is not really a problem for me to ride like this. I’m at over 170k miles, riding most days since 2009. I can tell what is going on around me just by sound at this point. The people behind are not the real problem. It is the u-turns that will get you. I’ve had 2 bad crashes out of 6 total and both bad ones were u-turns.
