Because it has to be repeated again and again: We need to drastically reduce the number of cars to solve our problems.
@AndiPopp so true. My main issue in adopting public transport as a means of travel for work is that most of my work isn't near stations, bus services are infrequent, unreliable and expensive. Also, as a photographer, I carry a lot of equipment.

Got to agree, Tim. I'm a wildlife photographer, and an angler: I can't (God knows I've tried) rely on public transport for either of these in my part of the world - SE Northumberland, England.

I've lived in 5 large towns (not in-the-sticks hamlets) in my 62 years, and NOT ONE of them was on the UK rail network.

Buses? Desperately unreliable, and none go anywhere I'd want to.

I ride an e-bike, but it can't get me and my kit ANYWHERE NEAR places I want to visit.
