DUmmy rsmithnumbers's problem with reverse gear is very real, and was detailed by smittynumbers himself.
After attending a scam truck driving school for two years, he left to begin his shuttle bus career.
Unfortunately, reverse gear was part of the third year curriculum, so rsmithnumbers twice failed the test for driving big rigs, due to inability to line up with a loading dock or to stop at an appropriate distance.
So his career as a commercial driver is limited to the route from the Hampton Inn to the airport.
