And if there's no other capacity on alternative modes of transport, trucking isn't key infrastructure?
What should also be done is looking at how the transport infrastructure should be shaped for the future. I think it is plausible that we will see a scenario with much more rail transport, with the final leg being performed by relatively small electric trucks with a limited autonomous range (but also by for instance coopting tramways in cities).
Building big new highways (as Zapatero is doing) will mainly favour mule power...
