Gear ratio effect on stopping/skidding

Another thought might be because you are a puny weakling like a malnourished ten year old. Harden The Fuck Up

Keep trying to lock those legs until it works. If you end up bouncing off a car or a lamppost just remember that whatever doesn't kill you only makes you stronger so it's good that you got hurt anyway.

The only other way to toughen up those spindly wimp legs is to to kick a copper in the nuts and run away.
