I wish I knew what the problem was with people not giving motorcycles their room. I see it enough, usually the retirees, pulling up next to me wanting to share my lane, eerrrrrgh! And then they look at you like, "What's YOUR problem!"
I'm afraid I would have not been so nice as to ride off. Of course, there is the possibility of being jailed for assult on a motor vehicle!
Hope your foot is truely OK!
later, Tom.
