It can be cool watching crews change a ton of stuff in a short amount of time to get the car back out. It also is cool seeing drivers overcome flats like Gravel did on Saturday to come from deep in the field to 2nd. But I'd be in favor of capping the type of work you can do in the work area to tires, wings and small suspension stuff. Just because you can change an axle in 2 minutes doesn't mean it's always possible, and then you get into the favortism angle of giving certain guys more time than others.
