Let’s not demonize driving, just stop subsidizing it

A typical car park is about 2.5m wide and 6m long, so 15 sq m. A typical car weighs about 1.5 tonnes, so the load on the floor of a car park is 100 kg per sq m.

I think it would be hard to exceed that with people, without breaking the fire code.

Design loading for human occupancies come in in the range of 100psf, which is something like 500kg/m2. That's roughly one 200lb adult per 2sf.

You can pack a _lot_ of humans into a small space.

Cars are about half that, because they don't pack well.

Of course, libraries are even worse, sometimes you're looking at 300+ psf design loads there.
