Just get rid of traffic jams and 9 lane highways, and diesel emissions.
Trains would actually sort a great deal if the network is wide enough and frequent enough.
You can, but can everyone else? I see quite a few disabled, seniors and pregnant people on trains. Not to mention people who are exhausted from their day.
I saw plenty of disabled and elderly and they all were able to take the buses and trains, and they used a cab for the last mile.
In contrast in the US, we don't have the transit at all, unless you live in a city like NYC, we just use cars everywhere.
Agreed, we should be making it easier and more convenient to take mass transit instead of driving. If improving last mile transit options beyond walking/biking helps to get more people out of cars and onto trains, that's a good thing. We just need to make sure we build enough mass transit to support that use case.
