I'm as liberal as it gets, but public transit that mimics private cars would absolutely be a game changer.
I don't want to have to interact with others using public transit. It's not the time nor place to "expand your horizons".
High speed rail with private cubes wouid absolutely get people using public transport.
No matter what everyone liberal / green / progressive claims, the main drawback of public transport is the public part. Listening to others bullshit and smells just sucks compared to the privacy of your own car.
