Will Smith/USR parallels notwithstanding, I think Tesla has another hit on their hands with the Tesla Semi. If the specs on the new Tesla semi are to be believed then they're going to be extremely popular. With ranges up to 800km/500mi and a capacity of up to 81,000lbs they're appropriate for more than the fringes of the trucking space. Given NO diesel maintenance requirements - not even a gearbox! In a semi! let that sink in - they'll pay for themselves in just a couple years of use so they're a no-brainer for a lot of transport situations. They'll certainly be a big hit with logistics and accounting departments but looking at the cockpit design, the ease of operation, and the performance I'll bet they're also going to be popular with the drivers themselves. (I'd seriously be interested in any thoughts from professional drivers on this video.) I can see Tesla selling as many of these as they can make and still not meeting demand. Mercedes/Penske and the rest of the recent entrants to the market are outclassed by at least 5 years on the R&D front too, so Tesla basically has the market to themselves. I can see why a number of them have retreated from the market now that Tesla's entry is here. Even if the others catch up on the R&D front, Tesla still has the battery supply wrapped up. Barring a repeat of the production problems with their Tesla cars, their semi line is going to be another money-printing machine for the company.
