Have you ever tried to pass on the right, but you can't see enough of the traffic on that side? It's because you're on the left side of the car, and that's the side you're supposed to pass on. With RHD, you can't see well enough to pass on the left.

Also, Have you ever tried to make a left-hand turn at a light through oncoming traffic, with opposing traffic directly in front of you also trying to make a left? With RHD, you can't see enough to make a safe turn, because you're on the wrong side of the car.

Merging onto a highway? You have more of the car obstructing your view when you look over your left shoulder.

That's not counting the details that are usually overlooked with a RHD conversion, like the side mirrors, which are now adjusted to the max (if you're lucky) to be able to see anything useful. The windshield wipers aren't usually switched over with it either, so they're going the wrong way too.

Basically a big old waste of time for what amounts to a talking point.
