The engine is the head rest. The wheels look as though they were sourced from a Grainger catalog in the caster section. Steering is accomplished by a push/pull lever. There are not readily apparent brakes. Putting those small details aside, this motorized creeper is just as safe as anything else on the road.
We have to thank eagle-eyed reader Mark Hovsepian for finding this video of a motorized creeper in action and passing the tip to us. Given the shot to ride this thing, our life span could be measured in minutes instead of years. That being said, where do we sign up to ride?
