When I was a newbie to the Duc world, a rider on a chopper passed me on my left as I was slowing to make a left turn.
Of course, I was piss*d but also astonished by the stupidity even a fellow rider displayed. I had been riding on the road for a few years but it was then that I realized, you can't be surprised by anything! Just expect crazy things WILL happen out there and keep your wits about you the best you can.
Remember not to let anyone p*ss you off or send you into a roadrage with their careless actions. Then you become a stupid rider too!
