Sometimes, a hitch might be retasked for something other than traditional trailer towing. Load platforms are one excellent example,
bicycle carriers are another;
and the previously mentioned pusher trailers are another. Of course, pusher trailers don't have to be petroleum-powered. For some designs, chicken nuggets will do just fine.
Sometimes, there really is a trailer that needs relocating, and it's just the tow rig that needs substitution.
And you thought I was joking? After all, my buddy needed the Burley, and it's very cold and foggy tonight!
With such capabilities, who could blame an EV for copping a little attitude?
