jeff,
If speed is the primary cause for this happening, most of your newer models have an optional feature that will limit the top travel speed of the unit. Most are factor installed options on engine powered units. On battery powered trucks the top travel speed can be adjusted via a hand set or lap-top on newer models.
Understand the union issue (been in and/or around UAW, United Steel Workers & Iron Workers shops) but most unions are behind safety of workers- if one of these "NASCAR Wanna Bees" takes done a column the chance for a major casualty is very great. Some one can discuss this with the union reps, if this a big problem - show them the facts..
