Seems dumb but the truckers both in the USA and England have had the politicians of all flavors wrapped round their little fingers and the rail network has been screwed over for them so to a degree it is Karma also in the UK heavy transport uses way more fuel in tons than private motoring so what is needed is an even handed look at transport, no hope of that!
Makes sense to me - Diesel is the most efficient method of powering transport available to Man, so of course we have to make it illegal or impossible.
Maybe California can get by on unicorn-powered trains. The farts can be collected to feed the people - unicorns DO fart Skittles, right?
This is right up there with requiring a fixed percentage of their power be made by unreliable wind generators while tearing down reliable hydro plants.
California deserves to slide into the ocean.
