Problems with being anthropomorphic: broken tail bones are very common. Often anthropomorphs dock their own tails in an effort to further their acceptance in a humanoid world.
Below: a rodent driving an automobile! So crazy!
Actually I think he is just sitting in it, not having the mental capacity to actually drive a vehicle is a usual trait in rodents. You can tell he is not driving because there are no little exhaust clouds coming out the back end of the car.
Also of no interest, I have unearthed a bunch of comics I did when in the angst-ridden years of high school. They are craptacular! You will have to be rather bored to do so, but click 'em to big 'em.
