You expect a high speed train station outside your front door? Awfully optimistic of you.
IMO the addition of birds and limes has been really nice.
Cost of living drops off as you leave metro areas. Like another responder to your comment noted: people pay for convenience. I'd say cost is a disadvantage of living in a high-density area.
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.
