I got to borrow a bike today and I biked waaayyy longer than I meant to because Christchurch's biking infrastructure is AWESOME, it's super flat and easy to bike here, and I am still constantly guessing directions wrong because I'm in the opposite hemisphere I'm used to (took the "scenic route")
Extra bonus points to me for not making any dumb mistakes while biking on the opposite side of the road from what I'm used to, while in traffic, in a city!
