As someone who lives in LA and flies to Asia often, I know that when you're flying out of LAX there aren't that many international gateways, and every night there are at least four jumbo jets that fly to Taipei (they all depart around midnight-1 am), and this allows for tons of connections within two hours of arriving in Taipei, so it's very likely that this is just the gateway city through which the teams connect to their next flight, which could literally be anywhere in Southeast Asia, the south pacific, or china. The only cities where it wouldn't make sense to go through Taipei would be Tokyo, Shanghai, Beijing, Bangkok, or Seoul, plus a few others, because they have direct flights.
However, a Taipei leg makes complete sense logistically because those midnight flights all arrive at around 6am, giving them a full day to race. Plus it would allow them to tie it in with the task they did in LA, like if they were given an object at the temple that somehow relates to the roadblock, like the way teams got a package of tea in china last season that became the theme of the next roadblock in Kolkata.
Very exciting to have the race going on now! Time to marvel at the detective work...hope we get a lot of spoilers this time!
