> Road wear increases with the fourth power of axle weight iirc

That's not actually true, and the paper that describes the "fourth power" thing even says that right up front.

If you massively oversimplify the model so that you've got all vehicles fitted with infinitely hard bicycle tyres on a perfectly smooth surface, it kind of works out, but not quite.

Interesting! Nevertheless I believe it is true that bike and pedestrian paths are much cheaper to construct and maintain than roads for cars and trucks.

[ErroneousBosh]

Probably.

How do you plan on getting food?

[adrianN]

Most roads are not used for delivering goods, so if we'd just reduce private car use that would already be a great improvement. If you want to go even further, rail has a lot of potential left.

[ErroneousBosh]

Interesting, can you give an example of why you think that?

How does food get to the shop at the end of your street?
