To compensate, in your case (LHD), either the passenger has to lose a little weight or the driver has to gain a little weight,
in my case it's the other way around.
The weight of the number of people on one side or the other of the planet also influences, it seems that the population of my Indian friends has increased considerably, fortunately the Americans (USA) and lately also the Mexicans compensate for these small imbalances in levels.
I can always joke with the Indians, they are very wise people.
Namaste.
