I'm not suggesting anything except that given two roads in a spherical universe, both going to same hypothetical place, I'd expect the one built for cars to be larger than the one built for bikes due to basic logic. Your response, and several of its ridiculous peers are just stuffing words into my mouth.

As to the OP's point, we reap what we sow.
