It seems that at nearly every intersection, the idea of using turn signals is something that never enters someone's mind. To anyone who rides a bicycle or moped, this fact is painfully obvious. The more you ride, the more chances you take. I don't worry about parking, I zip past traffic stuck in gridlock and most importantly, I get exercise. Thankfully, I'm not riding to Aloha Tower five times a week anymore.
Bike riding is meant to be a fun and healthy form of travel.
It is not meant to be an extreme sport. Turn signals are free and easy to use. So please use them. There are too many bad drivers on the road. This is another plain fact of driving.
