I really, honestly, never thought about this and it was never a problem.
Then again, I rode with platforms and ONE strap (just the leg that pulls up for counterforce).
So I was always able to move my feet around and maneuver around the bike if necessary.
I would also try to not dismount for as long as possible and that would require lots of hopping on the rear wheel to reposition for a trackstand so I never had that stoplight problem.
Idk man, sometimes I would stand on just one leg and wait until the crank arm lifted me high enough to effortlessly bring my leg to the other side.
You could also "dip" the bike down sideways while you kind of fall onto one foot if you needed to dismount.
Yeah idk, never thought about it.
