Its not dumb. I have seen pictures of similar devices made out of rubber or plastic materials. The drawbacks are remembering to deflate them or open the doors to which they are attached before getting to close to a loading docks and other objects. Also they cost some $ and only last about 5 years.

Another problem is that independent truckers ( who pay the fuel bills on the runs they make) often don't own the tractors they haul. One solution is government requirements or incentives to tractor manufacturers.
