Blinker control should be a stalk pointing to the driver's side door and self cancel.
Curious on your opinion where it should go on right wheel drive cars (and no, I don’t think converting the population of a whole country to “fix” it is realistic). I’ve seen it on both sides and it's somewhat funny to rediscover.
on RHD cars it depends on the market. Japan has it on the right, UK―on the left. It's a mess.
