A lot of tha Asian countries are RHD vehicles as well, such as Japan, Malaysia and Singapore. That's why you see Toyota Surfs and Nissan Silvia's on the road.
What side of the road do the Chinese drive on?
Because if it is a RHD car on the LH side of the road, give it 15-20 years, and the RHD cars will be in the majority again.....
Thing is, most countries allow LHD and RHD cars on the road. Europeans are all LHD cars, but the UK have RHD cars, and you have no problems putting a car on the ferry and driving them in the other countries. You can drive LHD cars in japan, and it is OK to drive RHD cars in the US. You can even register the wrong side cas in those countries.
In Australia, you cannot register a LHD car for use on the roads, unless it is older than 25 years and registered in Victoria. I am uncertain as to the laws, but I think it may be illegal to even drive a LHD car in Australia without some whopping sign on the rear.
