There is LITERALLY no point in shaving your legs if you're a layman. The only reason the tour de france fellas do it is so that if they crash they can get back on the road in about 8.3 seconds flat. The same as the reason F1 cars don't carry a manual wheel brace and a jack in the back and the driver has to jack it up on the verge and change the tyres himself.
So shaving your legs is actually the cycling equivalent of carrying an F1-standard, automatic, 4-bolt motorised wheel-unscrewer completely filling the boot of your car wherever you drive.
