Didn't you hear? Every one that wants FSD (beta) can have it. Getting it to actually work is just details.

I think you meant 900Kwh (250wh/kg*3600kg = 900,000wh = 900Kwh).

900Gwh would power 30,000,000 homes for a day, that's nuclear power plant scale energy.

Using my EV as a base (assuming range is proportional to vehicle weight) I get 113 mile range for a 33,5400kg vehicle and 3,600kg of batteries. To squeeze 500 mi range must have taken some smart regen braking system + very low wind resistance design.

Very low wind resistance it is. Weight is actually not the biggest factor with consumption as it only influences rolling friction and at highway speed it is mainly drag that is the biggest factor. A fully loaded 82k lbs Tesla Semi is actually 2x more efficient(mpge) than a Ford F-150 towing 9000lbs. See:

There was a shark tank pitch showing a suspension based Regen system and they said truck drivers aim to use brakes as infrequently as possible, which makes sense, but they said there is enough energy generated from the suspension to make a difference

Imagine the molten slurry of fire produced when an 82 ton raging SEMI crashes while the operator is in the sleeper cab with a Corinthian Maiden because F.S.D. was never viable.

Good thing that FSD vehicles have a tendency to slam into fire trucks/cop cars.

To be fair they only weigh 41 tons, but I imagine the fire could take out a city block. Something our ruling class might want to take a look at.

More worried about hydrogen trucks burning or if it's carrying fuel. But nice way of mixing different TSLAQ seeing cracks into a sentence. What's your prediction for GAAP earnings in Q4? I'm gonna guess $5B. You a lot lower?

Diesel fires are rare, but they can be put out. Li fires basically cannot be put out, and need to burn themselves out. Probably more toxic as well, but I'm speculating on that.

You have some source for that?

The fires with batteries take a lot longer to put out, that's better than a quick explosion at least with regards to lives of the people involved in the crash.

It sure seems like Tesla's burn all the time, but that's because the media reports every Tesla fire but seldom bothers with the gas cars burning as they are so commonplace.

You might want to include diesel fuel in your reply since we are discussing diesel.

Diesel fuel, IRT explosion risk, is much safer than gasoline. It can also be produced from plant matter via transesterification, thus providing a net zero CO2 fuel, e.g. biodiesel.

The primary criticism of diesel fuel is NOx byproduct during combustion. This was the source of VW Dieselgate.

You mention Li battery fires take longer to put out. Do you have any evidence how Li battery fires are put out, other than simply letting them burn out?

Feels like it isn't going to be so cool to own these things and very quickly. Maybe I'm wrong but the type of people that buy these cars aren't gonna wanna risk being socially ostracized in polite society upscale suburban circles, especially once comparable options are available from other companies.

They're going to have to maintain kickass product superiority at the very least. Some justification for the headache that you own a car and the CEO of the company might go full blown Trump/Kanye at any moment. Who the hell wants that hassle over a ****ing car?

I wonder why Elon didn't invest the $44 billion straight into the arteries of Tesla.

How many Gigafactories and/or obscured emergency door release handles could he have right now?

He's just so greedy too, not to have TSLA pay dividends.

Pays No dividend.

Bought Tesla at 164 Last week and
more at 157 this week.
Officially down more than $100k USD since I started buying Tesla pre split.

As for the battery fires, either you let them burn out, our you spray them with lots of water for like an hour. I think newer batteries, LFP etc(which now is the most common type) will be easier to put out. 4680 has tons of pink foam which is a fire ******ant around it. Not sure if we have seen any 4680 fires yet, but will be interesting to see.

Since you were trying to show how fire risk in semis is reduced with EVs, I will leave the diesel/ev comparison stats to you. One point to consider: throw a lit match into an open container of gasoline, and you will likely have an explosion. Throw a lit match into an open container of diesel fuel, and the diesel will put out the match.

Not enough, unfortunately. I posted in the politics thread a few reasons why this is so.
