China is pretty good, but the only place I've ever seen proper turn-up-and-go HSR is Japan. Tap your card or phone (NFC-F, because credit card contactless is too slow for Japan), walk on. If you missed the train you were aiming for there'll be another one 7.5 or at most 15 minutes later, so no big.
