Wow you think that was a personal" assault" ? We have a name for people who are offended and feel assaulted by every little thing other people say , we called them pussies . Does that offend you Pussy ? Your the one not reading, I clearly responded to what your problem is with the tech in question .The difference in range is moot when you figure the addition of solar charging panels on the trailers , the ability to drive at night and charge while sleeping in the day and the fact that you can't legally drive 800 miles in one go based on the 10 hr law and the legal requirements for all trucks to have trackers and data loggers in them .Why do you think they are targeting 500 miles ? because they know that's the limit under the law when you include a 1hr meal break during which the truck will be charging .Keep living in your ever shrinking bubble bud , the world is evolving around you and without you , maybe your boy Trump will mandate a coal powered car for you .
