If people aren’t driving cars down a road because stopping at so many stop signs is unpleasant, why do you expect cyclists to bike down that road, when they actually have to physical work (not just pushing a pedal) getting up to speed again? Stop signs suck for bikes more than for cars. If cars avoid a route because of stop signs, of course bikes will avoid it!

Vector mathematics as we use it and code it is based on the right hand rule.

Agreed. That would be totally valid.

The top one is wrong because it violates the right hand rule.
