For a product review you actually need the product to review. The jokes are about the concept of a table attached to a critical automobile control system. Yeah, I think we can assume that it was designed for use with the car stopped, but really... If it fits your steering wheel correctly and your seat gives you a good position relative to the tabletop and you actually do work in your car that a table would benefit, then get one. I would not buy one based on the 5 Star product reviews from Amazon; OTOH if I was in a situation where one might be useful, I wouldn't let those reviews stop me from buying one.
