One bit of advice I found useful is: don't stare at the rear wheel of the bike in front of you. Look at the seat post or some other stationary part instead. If you stare at the wheel, or the pavement going by, you get sort of hypnotized and end up drifting off the road or into the guy/gal in front of you. Havin done that on more than one occasion back in the day, I can tell you it's no fun.
