GPS route using "No Left Turn" algorithm?

seems to me that three right turns will put you a block back from where you want to go?

This would be especially useful when navigating large cities.

UPS has huge success using this algorithm. Why not the rest of us?

How UPS Trucks Saved Millions of Dollars by Eliminating Left Turns

Well UPS did this to save time and fuel, they figured less time waiting to turn saved fuel. They also were able to route so they were still picking up pickups and delivery's into the route.

In an RV making a left turn is easier than a right as you have more swing room. More than one semi has run over the front of the idiot driver that tried to cut inside of them when needing to pull to the left to make a right turn. Doesn't matter that they have their right turn signal on and a big message on the right mud flap stating makes wide right turns.
I have a right turn in a small town that I need to make on the way to the coast, because I am turning onto a one-way street I turn into the far lane.

You NEVER have to turn in front of oncoming (close by) traffic.

Just wait until there is a BIG break or wait for the light to change. Most high traffic areas have left turn lanes and arrows anyway.

If you guys think making that point is funny.......it isn't.

You go one block PAST the left turn intersection and THEN make 3 rights. I think most people could figure that out for themselves.

Be sure to tell that to the next person who turns left in front of you. Happens all the time, even when you think you've looked and then looked again. I've never pulled out in front of anyone but I've come close a time or two. Not turning left eliminates any issues.

You may have done it yourself, most who do it are totally unaware of what they've done.

Nope, if you go through the intersection where you need to turn left and turn right at the next block, then turn right at the next block, and then right again at the next block, you'll go right through the intersection going in the direction you would have if you had turned left initially. This, of course, presupposes that the blocks are equal and you can make those turns.

and does the gps automatically have a limit as to how far forward you have to go before it switches back to a left turn. as you say , easy in a normal town with standard blocks/roads but could be problematic out in the country or more rural areas.

UPS uses , as already said , a delivery route plan that incorporates mostly right turns to minimize delays ... the driver makes a lot of money sitting and isn't delivering not to mention the gallons of fuel saved by not idling thousands of vehicles . That's why the I.E. (industrial engineering) dept uses it. For efficiency! I don't think "easy" for the driver is considered but I'm a bit jaded :) I'm not in a hurry in the motorhome and burning a little more fuel , as I'm not driving a repetitive route every day , doesn't matter. But hey whatever makes it comfortable works.

Presuppose also that those 3 streets are actually passable for an RV.....AND that the "blocks" are not a mile long or more.

Exactly. And unless you have a need to actually go right, as in a route, you will burn more fuel by not turning left.
