Is the OP certain the speed was 160 kph? Some speeding is pretty normal but that is almost 100 mph and would be very unusual IME. I agree that the hotel should be made aware of it - if you are sure of the speed.

I also think that some of the very highest end services have probably become somewhat accustomed to automatic tipping by clueless westerners. It doesn't take much to move from "accustomed" to "entitled," which is why so many areas that do not value tiping are so strident about avoiding it. That sense of entitlement can be very hard to reverse once the "apple" has been tasted.

Of course, when you stay at cheap business hotels and dine at cheap neighborhood pubs and itzakayas like I do, you don't ever have the issue come up. And you often get better food in the bargain.
