I lost all pretensions the day I watched Tour De France Rider Laurent Fignon ride past me at about 18/19mph....up an Alp!!!!! He'd been racing for about 6 hours before our paths crossed.........
Anyone who never made an arse of themselves at lights, or trying to dismount in a dignified way, whilst using new pedals, probably doesn't ride much........
-and if you never got dusted by an older rider, on the way home or at the races, well, you still ain't riding enough;-)
