I've been on the Tokyo Disneyland Speedway several times in the last couple decades. They had a nifty feature to prevent bumping; if you came within a foot or two of the car ahead of you your car would come to a stop. It was impossible to bump the car ahead of you, because bumping is impolite. I hope they bring that feature to WDW's Speedway, which may be why they've shipped the cars over from Tokyo's closed version. You obviously haven't been to Japan lately. They are quite noticeably behind America when it comes to the middle classes ownership and use of new technology; smartphones, Apps, web-based services, mobile technology, home TV tech, cable and Internet, etc. Tokyo Disneyland, for example, doesn't have a wait time app. There is no public WiFi available in the Tokyo parks. They don't have any form of electronic Fastpass (MagicBands, Maxpass, etc.), you still just have to pull paper Fastpasses one at a time like it was 2002. Websites are all circa 2006. Cash is king and it's harder to pay with credit cards. Uber (as we know it, it's just a taxi-hailing service in Japan) doesn't exist in Tokyo, you take the subway or your own car to the park. Etc., etc., etc. I know, right?!? What's the most fascinating, is that there are Americans in 2017 who still think Japanese society is so far advanced than America. It's the exact opposite. The Japanese should congratulate their PR teams from the late 1980's who got that marketing concept going so strongly that it still has legs in 2017. Japan is a lovely country, and their Disneyland beats the snot out of anything we have here (maintenance, cleanliness, service, CM appearance, entertainment). But when it comes to daily use of technology, especially for the middle classes, they are a decade behind how the average American lives.
