Genuine question but how are any of the workers supposed to cart around a ton and a half worth of tools and equipment up and down the country to keep infrastructure actively providing the residents with power, water and prevent sewage flowing through their streets, if not for a car?
I know that cars are horrendous things in both sociological and environmental impacts, but if you don't give a useful alternative, then what are you arguing?
(I know electric vans exist, but if you've ever used one professionally then you know just how bad they are for anything that isn't inner city short hop driving. Without even mentioning the impact of producing an electric vehicle in terms of mining the rare earth materials for the batteries and electricity, or the added mechanical strain due to increased vehicle weight)
