Considering Tesla is depending on it's image to get more money to fill the gap of it's ever deepening losses, spending days preparing a presentation is the best use of his time. Tesla has a price-to-sale ration of nearly 6, while Nissan and GM are <0.5. So Tesla is mostly image and vision, not reality. Therefore it depends on Musks presentations with visions of a glorious future.

I don't think Elon Musk's plan is to build up Tesla as a huge pyramid scheme, cash out at the peak, and move to Mars before he gets arrested. He is running a couple of very technical companies and is down in the trenches working 80-100 hours weeks to keep them moving forward as fast as possible. Getting the Model 3 up to a production rate of 5,000 a week is what will start to prove out Tesla's current stock price, no…

I didn't want to imply that, it's more about staying afloat.

"Getting the Model 3 up to a production rate of 5,000 a week is what will start to prove out Tesla's current stock price, not a slick demo."

Yes, currently it looks like this is out of reach of Tesla.

The entire reusability thing was not really a thing before spacex

There was already a working program that had their funding axed: Here's a video from 1995: https://www.youtube.com/watch?v=wv9n9Casp1o . There were others too.

To answer your deleted question, there would be no point in listing their achievements for you because you're obviously determined to ignore them, and having them listed for you won't change that.

Is a center seating position common for truck drivers? It looks amazing , but it is different enough from my normal consumer driving experience as to make the entire product a non-starter if it were in a consumer car. I've developed decades of training and muscle memory sitting on the left side of the car. I wonder if there will be a measurable impact on accident rates.

Mclaren is a consumer car with a center seat: https://www.google.com/search?q=mclaren+center+seat&tbm=isch

It’s hardly mainstream. It’s a $1,000,000+ hypercar.

Have you forgotten Job's reality disortion field? Sometimes you gotta get people to believe in a better reality :P

Tesla obviously has to and always has.

  "[...] as long as 1) wealthy consumers in western
   nations but also China are eager to seek indulgence
   by way of green-washing and, 2) are in search of a
   Steve Jobs replacement persona onto which they can
   project their hopes for a gleaming future and, 
   3) are disillusioned with the establishment and 
   its leaders, the company will likely succeed to 
   raise cash again."

It wasn't really from scratch though was it, he hired out people who had already worked with space projects. None of the tech is really new (yet). We used to have the same types of rockets in the past. Amongst Model 3 fiasco Solarcity too currently has issues.

It's incredible how you trivialize SpaceX achievements. I get it that you probably hate Elon Musk for whatever reason. But you should really calibrate your bias filter.

I love some of his other achievements with Tesla and with solar roofing tiles, but SpaceX has a lot of hype surrounding it.

Ok as a mechanic a few million questions: * What happens when a wheel seal goes? Do I have to remove all that ridiculous plastic on #2,3 axels?? * What happens when a tire blows? Is it going to destroy all that plastic and take out a few more tires in the process? * Why all the glass? I've spend entire days replacing windshields for a 12 or so truck shop which generally come in two (drivers and passengers), the Tesla…

You should probably watch the actual reveal, it's already on YouTube. The glass was already addressed and he gave it a specific focus. Even claiming it can withstand an atomic blast.

Yeah that is just classic "what sounds really impressive but actually isn't that bad" marketing nonsense.

It might be able to withstand an atomic glass but it's still going to crack if a big enough stone his it at 70mph.

He states that they have spent a lot of time talking to truckers and truck companies. I would guess they believe that with an electric drive train repairs and maintenance will be an order of magnitude lower (not sure how that works for tires and wheels). Body damage should also be much lower with automatic breaking and other features of enhanced autopilot. As Musk said, broken glass is a big cost for trucking as you…

Over the last centuries there were a number of truck and bus manufacturers who tried the single/middle seat design. It was never a seller for any of those. If you take someone with you, you don't want to sit him/her to sit behind you. You want them to sit next to you. If you are on the road in the city, you have often colleagues with you, like in a moving company and alike. Such trucks are used in construction work w…

Could it be that this semi just isn't meant for those in-city hauls, but more for the longer-range highway hauls?

"The quickest acceleration—from zero to 60 mph in 20 seconds, fully loaded."

sound of cargo falling over :P

But serious question: how important is acceleration for trucks?

Because of economics of scale, you design one versatile truck chassis. That can then be easily modified like longer vs. shorter for the super structure, the driver cabin is modified in size so that you have a sleeping possibility or not and all those things.

Just take a look, the very same long haul truck is also used by the construction workers. Only the the cabin is a little bit shorter.
