I never do but I'm a 'noob' anyway. My first time through the Gap I was followed by a guy on a motard (who said he rides that road every day). He stayed fairly close but gave me plenty of room as I was uber nervous on my V-Star. When I stopped at the store to gather my wits he complemented me on my smoothness and speed (for a cruiser).
I thought it was very generous of him to say those things since I was working VERY hard to do it right!
