High speed rail can’t do multiple quick stops. So, you can get to a city’s center with it, but acceleration and deceleration times plus station time means you are stuck with subways for in city use. You can’t use high speed rail and and a subway system to move very far and still have a 45 minuet commute.

So, now you need to live near HSR and your job also needs to be next to HSR in order for that trip to work.
