I live in Florida, only an hour from Daytona Beach, which is a haven for bikers. We tend to travel the other direction during the weekends before and after Bikeweek and Biketoberfest. It can take miles to get to a point where a car can switch lanes, because some of the groups are so large and/or scattered in a single file line. This is few and far between, though. Most bikers I encounter are great drivers. I am very cautious around motorcycles, for the cyclist's safety and my peace of mind.
I will be buying a motorcycle in the next few years, and I will endeavor to be a courteous motorcyclist.
