Thanks for the good points.
What about pedal placement benefits of right hand drive, as in are there any?
Any benefits to shifter placement on right hand sill, as in better linkage arrangement to the transmission?
I haven't noticed any differences with the pedal arrangement between LHD and RHD cars.
I've had four RHD cars in the US. Driving the GT40 (RHD) with the shifter on the right is much easier than driving a RHD car with the shifter in the center because shifting with your right hand is what you'd do with a typical LHD car and a center shifter, so the reflexes are the same (except that 1st gear is towards you, not away).
Another one of my former RHD cars was a saloon car with the engine in the front and shifter on the right. I remember being told that the LHD version built for the continent had a center shifter, but they then ran the the linkages under the floor to the right side of the car to join the existing linkages where the RHD shifter would have been. The LHD shifter with three right angle turns was a bit sloppier than the RHD shifter.
Once, I when I was a teen, I was a passenger in an RHD car, we got pulled over for speeding. The police man came over to the window on the left side of the car and spent a minute yelling at me for speeding in a residential neighborhood. When he stopped yelling and asked for the license and registration, all I could do was point to the driver on the other side of the car. At that point, he ran out of steam and was a bit more subdued when he spoke to the actual driver, who got a warning. So that might count as an advantage for driving an RHD car.
OTOH, if you might drive an RHD car on a toll road, I strongly recommend get an EZ Pass transponder so you don't have to deal with paying the tolls when you're sitting on the "wrong" side of the car.
