The whole world should drive on the right (i.e. the left) side of the road.

Thanks for posting your argument.Pro begins by stating that switching from being a right-hand-side country to a left-hand-side country would only require flipping road signs around and repainting road direction. He states simply that we should imagine watching traffic footage backwards, and this shows how simple the change would be. I should note that I backed up the fact that many interchanges and such things with a source (#2 in my previous argument) but Pro insists that switching from right to left is as simple as flipping the signs and paint around. Here's a random section of roadway I zoomed into on Google Earth that immediately has a problem that jumps out at me: The arrow is pointing out a TURN LANE which is necessary to allow traffic to turn into the strip mall. Why is it necessary? Because if it weren't there, traffic, especially if heavy during rush hour, would have to slam on their brakes to allow a motorist to turn into it. With the turn lane, motorists who are going into the strip mall can slide into the lane without endangering or slowing down traffic behind them. If traffic were to flow the other way with the road in its current state, motorists would face the very situation that the turn lane is made to avoid. Not to mention, a whole new turn lane would have to be put in and perhaps the old one stripped up. I remind you that this is a random section of road I found on Google Earth (I can't even remember where I found it) and you could probably find many more similar situations if you play around with the program for a while. So, this is one more example of a road situation that would require correction if the U.S. were to switch to the left side of the road. Pro brought up an interesting fact about why many countries drive on the left-hand side of the car. Thanks to Pro for sharing this cool factoid with us. But he says: "these days people carry guns instead, and shooting a motorist that has irritated you in some way is so much easier sitting on the right-hand side of the car than the left, at least for people who are right handed anyway."One point I'd like to make about this: I see from my opponent's profile that he is Con in the gun rights category. I DO NOT intend nor wish to make this into a political discussion, but here's the deal: if my opponent opposes gun rights, then why would he advocate a change that he admits would make it easier for someone to shoot a motorist who happens to annoy him? I'd like to make one final point in conclusion. Going back to my opponent's claim: "Now, if only everybody drove on the left-hand side of the road billions would be saved in development costs and we would all pay less for new cars."We both seem to have missed a very important effect of a switch like this: what in the WORLD do we do with all the cars that we currently have?? As of 2011 there are 253,108,389 registered cars in the United States. [1] If we mandate that all drivers must begin driving on the left, we must either a. scrap all of them and import right-steering-wheel cars, or b. convert every last one of them to right-wheel configurations. Option A means scrapping 253 million cars- a huge waste that would send Al Gore to a mental asylum. Plus, I don't even want to think about what the cost of importing replacements for all those cars could be.Option B: searching eBay for the correct RHD conversion components brings up parts that cost around a thousand dollars! I don't even want to think about labor costs for getting a mechanic to do it- he'd have to strip the dashboard and replace the entire steering column. If you had a Camaro imported from the USA to Australia and converted to RHD, it would cost $96,915. [2] [3] Thank you for the opportunity to do the debate. [1] http://www.rita.dot.gov...
