While I agree an 80 hour motors class would be ideal, civilians are not allowed to attend unless they have PD connections. They also have an enormous failure rate.
Midwest looks to be a great alternative, but to achieve any where near a motors level it takes three classes, three weeks of time and many thousands of dollars for tuition, accommodations and travel that most wouldn't invest.
The RLAP classes offer a good alternative for cost and training. Although nowhere near the training of a four day class, cost and time investment are more enticing to the general riding public and therefore more will train.
Any type or amount of training quickly fades away without practice, but at least not completely to a pre class level. Although they ride everyday, most in motors don't practice unless entering a comp. or getting re certified, but they are easy to spot amongst those who do.
