Does typical navigation software assign the same cost to a left turn as a right turn?
Most software will weight on rules like how long it will take to turn left rather than right at an intersection, and other average case rules at decision points.

I don't know of any other country than the US where turning right on red is allowed, unless there's specific signage or additional traffic lights to allow it.

Turning right on red is one of those idea that once you've been exposed to it you wonder why isn't everybody adopting it... A similar idea is the train system in Munich where they built their platforms such that they can open doors on both sides, making one side of the train the exit, and the other side the entrance. Ever since I saw that, every single time I wait for people getting off a crowded train, I wonder "Why…
Because someone who comes from your left may go forward, or someone who comes from your front mau turn left?
Where I live, we do not assume that we can turn right on red lights. Where and when that's possible, we have a blinking yellow light (basically meaning proceed with caution)..

It gets even better -- you can also make an "Oregon left" - in Oregon it is legal to turn left on red if you are turning onto a one way street. http://www.oregonlive.com/commuting/index.ssf/2015/10/turn_l...

It is legal to turn right on a red light in Canada, except the Isle of Montreal. It actually used to be illegal in all of Quebec until 2003.

As for someone to your left going straight thru the intersection... you, turning right, must yield to those going straight. However, there is not always traffic coming straight through the light. If someone on the perpendicular street turns right instead of going straight thru, you may turn right from your lane into their lane because there is a pause in traffic flow coming through the intersection.
That probably doesn't make much sense but the bottom line is that when everyone knows the rules and everyone observes them, right on red is mostly painless.
It would be an interesting experiment to see how different consumer grade satnav systems compare on this pure travelling salesman problem.

Er... I understand that you may reduce your fuel consumption by not waiting at red lights, but that the total distance driven has been reduced is clearly wrong!
Guys, you have a bug in your spreadsheet!
