I disagree ... every car on the road has its steering wheel in the same plac. Every car has its gas and brake pedals in the same place and configuration, and its driving controls on the same side of the car.
There is also plenty of room for variation in a DIR configuration ... but not in how the fundamental operating gear is placed and configured. Just like a car.
