Do modern cars no longer lower the drive shaft as in this video? I haven't really seen a sedan with a flat floor in the rear for some time (ever, in my lifetime anyway). Is it just that the floors have been lowered so much that you can't really lower the drive shaft any further?
modern cars are much lower than cars from the 30s. the driveshaft pretty much has to be recessed into the body to give any useful ground clearance and to protect the drive shaft from speed bumps and road hazards.
