If someone is going slower than me I pass them (usually with a "Hello"). If someone passes me I usually say "hello". If someone is sucking on my rear wheel I say "hello" and if that person bothers me by getting too close, I slow down increasingly till they pass. I don't feel superior when I pass someone and I don't care what other riders are thinking especially about me. If you ride a bike on the road, it doesn't matter what brand or type you ride, it doesn't matter how slow or fast you ride, it doesn't matter if you wear brightly colored bike spacific clothes or your every day clothes. Its us against the motorists, were all in this together. That is, at least until the oil runs out.
