So why can't Google Maps eliminate stupid left turns from its vehicle directions? If they have information on traffic lights, then they could stop telling people to make a left out of a side street where there's no light. But if that's too difficult, they could just have an option for making routes with only right turns, like it's rumored delivery companies do. I was so hopeful that somewhere in the depths of their Maps API there was a way to customize the routing logic, but it appears not. Google knows best.
