Is this the sort of technology used in those (Tokyo) Disney rides, like Pooh's Hunny Hunt and some water-based one? Every ride seemed to be different, and the cart would just go and do its own thing.

Any tradesman in Perth/Western Australia should have a decent house and car as they earn more than our doctors and have a head start of about 6-8 years too. If they don't blow it all on alcohol. I have friends who paid cash for their first and second houses and they're only 24/25 after working on the mines for a few years.
