You ever wonder why North Americans drive on the right side of the road, while our friends in the U.K. drive on the left. Well it harkens back to the romans who rode chariots, they needed to have their right arm free to wield their swords so they would ride on the right hand side of the chariot on the left side of the road (guess it must have sucked if you were left handed). North Americans on the other hand, no pun intended, OK maybe a little, had to be on the left hand side because that was where the hand brake was located on wagons and carts.
I know this seems like a weird thing to think about, but the reason I looked it up was because I was shopping at the mall this weekend and everyone follows the same rules as driving,with people passing the other way on the left. Is this just hard-wired into our brains? Try to cut across the flow and change it up, you can see people getting agitated, kinda funny actually, its like we’re cattle or something. I wonder if people in the U.K. shop differently?
