I think that it would need to be combined with rooftop solar, which of course Tesla can sell them from their Buffalo plant in the near future...I don't disagree, but I really want to know the technical details behind how they pull that off - by my physics first principles calculations a semi travelling in a day what a semi is currently allowed to will add around 42kW of load-leveled load to the grid 24/7 PER SEMI. In most places, that one semi alone is nearly enough to start triggering demand charges of $500/mo+ from the utility
I think swapping the tractor would be easier and faster than swapping the pack. Why spend extra for all the equipment needed for a fast swap. The company owning and using the trucks could figure where and when to place replacement tractors.

Here's a cool video of Steve Jurvetson showing that it is motorized after all!
for those of us who don't want to gloat, this might offer an opportunity to practice,
Volkswagen brand CEO says Tesla has abilities Volkswagen lacks
This does not seem ideal since having trucks idle would tie up a more expensive asset than just the batteries. Also, having battery swaps (or an ultra-fast charging network) would expand the market so it is open to essentially anyone who wants the truck, including owner/operators. The same is true with current Supercharger charge rates but that would probably require more downtime and/or a bigger battery than a swapping system.
In any case, will be interesting to see which solution they choose ....

I agree with you, people need to do the math, but they don't trust their math.
They trust Dave Ramsey...
Someone said to reach out to him. It would be better if Tesla reached out to him, and they prioritized feature delivery based on his math.
On the last call, Elon said "There are a lot of people with the latest and greatest [battery].... If you want us to look at it, don't give us a power point, everything works in power point, give us a report on the [battery] from an independent test lab (ITL)."
If Elon wants to sell to the middle class, he should follow his own advice. Replace the word [battery] with the words [new car] and treat Dave Ramsey as the independent test lab (ITL).
The pricing on self driving will likely need to come down to $2K...
Anyway, I'll set the table. But Tesla will have to send it to Dave's ITL.
Thank you for a path to higher share value and long term health for Tesla.
...which there obviously will be or else Tesla wouldn't be doing it.Speaking of Fedex and UPS, I know from experience that both of these guys are watching the Semi as closely as they are allowed to, and running the numbers diligently to see if there is a business case for a fleet order.
I dont think you have ever listened to Dave Ramsey. His biggest bit of advise is to pay cash for an old beater instead of financing a new car. I dont think Dave Ramsey would be a fan of any luxury vehicle. I could be wrong.

It has to be motorized because the whole car is designed to be autonomous, including automatic charging. That's why the glove box can be locked from the software.
Most people, include many longs still don't believe Tesla is brining full automation to the market.
I honostly have no clue if they can build a long range Semi that does not required 2MWh pack to go 500 miles. But I do know that BYD has a class 8 semi that I assume is a less efficient battery tech that has a range of 92 miles with a 188KWh. If you can just scale that by 3-4, then you get close to the goal without having it weigh to much, cutting the load you can carry. Curb weight is 23,000lbs which is fairly heavy for just the tractor:
http://www.byd.com/usa/wp-content/uploads/2016/08/T9-final.pdf
If we can assume that Tesla's batteries + motor + inverter are 30% more efficient and energy dense at the same weight, Tesla could get 400 miles with a ~600KWh pack and 500 miles of range with a ~700KWh pack. 500 miles would be more then a full shift and would allow for some buffer. The Tractor would be very heavy, maybe as high as 40,000lbs with no load, so it could limit what it can carry, but it certainly could satisfy most of the industries needs and more then enough to allow Tesla to carve out a huge chunk of the market.
Also of note, Tesla could easily sell the semi at or bellow cost and just make profit from the charging or could include charging in the purchase price, which would be better for Tesla from a financial stand point. We are talking about gigawatts of charging at 20c per KWh and as long as Tesla can install microgrids at each station, they could have north of 70% margins on the charging.
