USA (obvs, coast to coast multiple times)
Canada (surprisingly horrible traffic in the big cities)
Mexico (most highways are fine, it's bigger cities that get all jammed up)
UK (terrifying to me, my passenger, and every other driver on those roads, and never again)
Israel (kinda nuts, but once out of TA it's fine; thankfully nearly all road signs are in Hebrew, Arabic, AND English but some in the older parts of town are only in Hebrew so that was fun)
Romania (watch out for the donkey carts, vampires at night, and drunks)
