First of WELCOME to the forum!!! Don't worry about the jerk motorist out there, they are most likely jerks to everyone else for one reason or another. I was more embarrassed about looking at myself in the mirror then what anyone has ever said about my weight. I personally have never had anyone say anything about my weight while I was riding, but have had a few horn honks about the way I was riding. So get out there, it is a great new world to experience on a bike, enjoy it !!!!
