As somebody who rides a motorcycle, I can't get over the dead weight that people drive around.
The average car in the US is 3500 pounds where as they're only using about 600 pounds of that weight at any given time.
Why the need to fuel all that dead weight(hauling around unused metal), times the number of drivers in America?
Why not optimize the weight of vehicles and therefore how much fuel (electric or gas) is needed to propell those vehicles?
I mean, in reality this thread was more to find out what kind of idiots would buy an old luxury car for the price of a new normal car, but this got unexpectedly interesting.
