I don't eat much salad and this isn't about the enviroment in my mind , solar has gotten a whole lot more efficient since the fifties and battery tech is constantly evolving , The truck doesn't need an 800 mile range because the Law only allows 10 hours of driving so add a trailer covered on panels and the truck can be recharged while the driver gets his required sleeps after his shift at the wheel . This is just about replacing one tech with another and there are going to be people like you who refuse to see the whole picture at once and want to pick at the edges of individual items but this is coming as a whole . Heres another one for you -there is no doubt in my mind you would have made the same arguements 40 years ago regarding computors , star trek communicators and Dick Tracy video phone watches but here we are walking around with all three built into 1 that is thousands of times more powerful than what was used to send the men to the moon 50 years ago . The Paradigm is the end of the fossil fuel oligarchy and the global control it exercises . Is Musk running in too many directions at once ? Probably but the market will find the help he needs to keep the balls in the air and we will move forward .
