Most people would kick my *** on the street (still unsure of how to judge that sort of competition??). That doesn't mean a damn thing when it comes to actual riding skill. All it shows is that I have the skill to keep myself in check and don't need to show anyone how awesome I am at riding a bike. Taking an on/off ramp at triple the posted speed or weaving through traffic doesn't show much when it comes to riding abilities but it definitely highlights that riders inability to process the risk/reward factor of their actions.
With that, you've come full circle to what I think @inreb was getting at.. Seems you equate skill with speed.. You're missing the point...
