actually, it does. on the sort of steel grate you'ere talking about the bike will shimmy, no matter what, but he's not riding on a metal grate, he's riding on pavement \a two wheeled vehicle balanced by pitting steering angle against lean: if you put the bike upright and let it go, it'll fall over if you push it,and it has decent steering characteristics, it'll start to fall over, and the front wheel, of it's own accord, will steer in the direction of the lean, causing the bike to come back upright, and start to flop over the other way: the faster the vehicle moves,and the more stability-centric it's front wheel rake and trail are the faster this cycle is, and at anything above a walk you don't even feel it when you grip the bars harder, you interfere with this dynamic, and actually destabilize the bike by preventing this effect this is why little kids on bikes start out tense and wobbly, and as they get better, become relaxed and stable
