Just came across this interesting article about the many benefits that UPS realizes simply by planning delivery routes to minimize the need for left-hand turns:
Why UPS trucks (almost) never turn left - CNN.com
Near the end of the article it is suggested that adopting such a strategy isn't usually as beneficial for us regular folks, but I disagree. I've been doing this all my life. If I'm running errands and making several stops, I always consider this when planning my route, and even if I'm just going from Point A to Point B I often choose the route with the fewest lefts. Granted that I'm probably not realizing great savings in fuel costs or emissions, or maybe even time, but at least it minimizes one source annoyance and frustration (and danger) when there's a lot of traffic.
