When driving someone to a destination on a two way street, most of the times it is not important what side of the street you drop the person.

Adding a configuration to choose between right side of the street (based on numbers) vs shortest route independent of the side could reduce many commute times, saving on emissions and road use. Having it as an option either in preferences or at trip level (perhaps as another option when reviewing the different routes) would have a really positive impact to the ones needing this feature without messing with the experience of the folks that consider the right side of the road important.
