Just keep a firm grip, and relax on the seat. There is nothing you can do about it. I've been riding for 42 years, and learned to sort of flow with it. If you fight it, and are trying to pull against it...what happens when it suddenly stops? You take off like a sling shot to exactly where you Don't want to go. Don't worry about looking like a drunk driver... Just let it move you around. Stay loose on the seat, and firm on the bars.
