Interesting question, great to see stuff like this here. >suburbs that WERE 1 hour away are now only 30 minutes away.. Possibly, though that kind of a speedup sounds wildly optimistic. I'd bet the more significant aspect of this would be the ability to get work done during the ride, which also has the same effect that you point out, increasing the radius of a viable commute. Still, living close will be desirable. Distance ridden is sure to be part of what determines how much you pay for transportation.
