Alola's challenges were more based off Hawaii and Hawaiian culture.
The Orange Islands and most of the island arcs of that era, were more like Okinawa and the other various islands and territories near Japanese Waters. Since Kanto is the name of an actual Prefecture in Japan.
We did eventually get straight surfing time races in Gen 7 but they were pretty dogshit, time consuming as in 5-10+ minute long sequences and it was just far easier to use fly to get from place to place. I missed having to have a party pokemon know an HM to get around.
The pocket machamp and taurus made no sense.
At least Omega latios and latias made sense having a homing beacon for them to pick you up with. Like bitch, you're telling me I can ONLY use 6 pokemon at once, but I have at least 10 of these mothafuckas in my bag just waiting to do various HM shit, one per move with accompanying tard tier safety equipment that ORAS didn't have.
