In countries which drive on the right hand side of the road, it is more fuel efficient for delivery drivers to never turn left. And UPS claims it saves massive amounts of fuel by following this philosophy, even if it means longer routings. “One of their methods is to try and avoid turning through oncoming traffic at a junction. Although this might be going in the opposite direction of the final destination, it reduces the chances of an accident and cuts delays caused by waiting for a gap in the traffic, which would also waste fuel.”
