The maximum speed governor would guarantee the longevity of the class and you could keep the fleet fresh with the sale of the value added used record holders.
We could package it with a "Modern Hero" photo package that featured a tech tard with his hand in your pocket.
We could call it "RENT A SLED".
How can it get any better ?
