Doing The Right Thing

It seems that sitting in the left lane, engine idling, waiting for oncoming traffic to clear so you can make a left-hand turn is wasteful not only of time and peace of mind, but also of gas and therefore money. This realization motivated UPS to limit the number of left-hand turns its drivers make.
In 2006, according to Heather Robinson, a UPS spokeswoman, route-planning software that reduced left turns helped the company shave 28.5 million miles off its delivery routes, which has resulted in savings of roughly 3 million gallons of gas. In 2012, by using routing technology and avoiding idling at lights for left-hand turns, UPS was able to avoid 98 million minutes of idle time.
Lehavdil, we find a similar preference for right turns in halachah. However, right off the bat we should note that it is for a totally different reason. The right was preferred even it did not save any time. The Talmud states (Yoma 17b), “All turns that you turn should be a right towards the east.” The Mizbeiach in the Beis HaMikdash was square, with a ramp beside it. When the kohein walked up the ramp, he was facing north. To his left was the western side, which had the Heichal and Kodesh HaKedashim; to his right was the eastern side with most of the courtyard. If a kohein wanted to perform avodah in the southwest corner of the Altar, he would walk up the ramp, turn right, walk to the southeast corner, and continue all the way around the Altar until he reached the southwest corner.
