200 people in cars, on bikes, on buses and light rail

The gif/video is glitchy for me but I get the point. It's obvious actually if you spend time on the road on a bike. I think everyone should be required to have experience on a bicycle before being allowed to drive.

Cars should be banned from city centres completely. There are some comments there saying "leave for car, enjoy the walk". Well, no, I can't enjoy the walk (or cycle) because of the cars. There needs to be top down enforcement. We all need to do this.

I'm always saying that but my family and friends treat me as if I am crazy! People are so used to their cars they can't even imagine an alternative system.

Where’s the 50 year old version of this?

They’ve been illustrating this for decades.

Missing: “In tunnels” :-)

Spending hundreds of millions to billions to cater for a hopelessly unsustainable form of transportation? Not good.

Underground mass transit is unsustainable? I don't understand what you mean.

Well, not mass transit, no. I thought you referred to tunnels for private cars, à la Musk's ambitions.
