First let me start by saying fuck cars, i dont like the fact that the world infrastructure is centered around them when trains (be it coal or electric) and rails exist. And now on to the rage baith:

I dont like that this pretty much shifts the reaponsibility from big corporations polution onto its workers, if delivery people had a union this would be an absolute no no, because its asking way more phisical push with what is going to be the same amount of packages with the same low pay with way more effort from the part of the worker, when we know that the polluting monsters are the companies they work for and the tech the companies employ and refuses to change into more sustainable ones, like planes, factories in some cases and the waste they produce and irresponsibly dump, be it abroad with uncaring legislations or locally. While i too would like a total redesign of urban infrastructure to suportt more sustainable transportation technologies, whe are gonna have to do with what we have (at least for the moment) and a better answer for that specifically imo would be fully electric vehicles, and in keeping with the taking less space theme, electric cargo motorbikes (the ones that dont have pedals). The same as the ones like the pizza delivery ones but with rechargable batteries instead of a gas engine.

Oh btw downvotes to the right.
