Is there a point where you've practiced enough?

I found this on the Net today and found it interesting. It tells why Motor officers die.

According to the Law Enforcement Memorial Police, Motorcycle accidents are the third leading cause of death for Police Officers. However, according to a study on PMO:

1) Improper Braking 33.6%
2) Failure to take Evasive Action 26.7%
3) Curve Negotiation 12.8%

In these accidents, 49.2% reported rider error was present. This is why accident avoidance exercises in conjunction with in-service training is of vital importance for overall safety.

It surprised me that with all their skill and practice, they still get it wrong and die due to rider error a lot.

What do you think?
