Also interesting that the Tesla cars use AC motors that are very similar in principle to the induction motor. Tesla cars (like the vast majority of electric vehicles) also operate on AC for all the traction and control side circuitry. Speed control is by varying the frequency applied to the motor. The only DC part is the battery itself and cables to the variable frequency inverter and to the AC charger, and that's only because we don't yet have a way to store AC.

Tesla attacks another other car when in autopilot mode.
A few bugs to work out of the system, and really, hitting a police car isn't a good look.

To quote the article "The carmaker says the function is not designed to avoid a collision and warns drivers not to rely on it entirely". Imagine an aviation autopilot not being able to fly a plane

Imagine an autopilot in a small aircraft being able to avoid a mid-air collision, or even a taxy accident...

It's purely anecdotal, but the petrol-engined vehicle fires I know of were nothing to do with a crash (e.g. a friend's old banger caught fire due to fuel leaking onto the engine while he was driving). So that comparison really tells you nothing about how likely a Tesla is to catch fire in a crash, compared to a petrol car... or how bad the consequences will be.

My pulled-out-of-my-backside guess is that petrol cars are far more likely to catch fire in normal operation, and electric cars with large lithium batteries are far more likely to catch fire after a crash. And, if they do, there's not a lot the fire crew can do to put out that lithium-battery fire.

Small lithium batteries probably won't be breached in the crash, and probably won't catch fire. But also can't drive very far.

But Tesla have it as a selling point on their website:

"Standard Safety Features

These active safety technologies, including collision avoidance and automatic emergency braking, have begun rolling out through over-the-air updates"

There's an interesting test of the Tesla "autopilot", conducted by Thatcham, here: https://www.bbc.co.uk/news/av/busine...t-happens-next

On the face of it, the test scenario isn't that unrealistic, and highlights what looks to be a significant shortcoming in the technology as it stands at the moment. The evidence from this video seems to suggest that neither collision avoidance nor automatic emergency braking function in that scenario.

To see what a Tesla thermal runaway looks like play the video in this article.

PS Not really having an axe to grind but just trying to keep things honest here. Elon Musk assured us that the configuration and isolation of the battery cells in his cars makes them much safer than those in the 787 Dreamliner.

I am guessing that the cause will have been something outside the box, pun intended, and Tesla will be just as eager as everyone else to find out the cause. This car could have been parked in sub-zero temperatures, destroying the integrity of the lithium. Or it could have been in a body-slamming accident and been repaired, or it could have been penetrated by some sharp object like an I-beam on the road as in the previously recorded 2013 Seattle Tesla fire.

Musk may have really stepped in it with his latest tweet about taking Tesla private.

https://www.msn.com/en-us/money/comp...cid=spartandhp

The SEC's rule 14e-8 basically prohibits publicly traded companies from announcing plans to buy or sell securities if executives don't intend to follow through, don't have the means to complete the deal or are flat out trying to manipulate the stock price.
If Elton can't back up his tweet that he can take Tesla private, he could well end up in jail...

From what I have heard Tesla has been plagued by large scale shorting of the price by what is assumed to be state sponsored market manipulation. Probably by those nations with much to lose following the growth of electric vehicles and lower usage of Oil.

There would have been some huge losses on these shorts after he made his suggestion and raised the price. Quite a good way to fight them back IMO.

I'm just not sure whether a tweet mentioning that he was thinking about doing something would be classed as an official announcement and market manipulation by himself.
Wait a minute - you just wrote that he 'fought back' by making a tweet that affected the stock price. Isn't that the very definition of market manipulation? How can you then write that you don't know if that could be considered market manipulation. SEC takes a very dim view of that sort of thing, and some very public people have ended up in jail for doing less. If Musk can't show meaningful evidence that he's pursuing the possibility of taking the company private (and show were the $70 billion would come from), he could be in very serious trouble.

Elon (or Elton ) doesn't seem to know when to stop digging (I recently made the comment that Musk is a geeky Trump and everyone agreed). His latest comments have caused the stock price to tank, and now the shareholders are suing...

https://start.att.net/news/read/cate...nipu-newscred2

"It was, at best, hasty and naive, and, at worst, manipulative,"
According to Sonnenfeld, Monday's statement doesn't lessen the chance that Musk receives some form of punishment from the SEC, in addition to lawsuits from shareholders, some of which have already been filed.

"It would be hard to imagine he isn't sanctioned, fined, reprimanded in some way for this misconduct," he said.
I think all involved would be best served if Musk would STHU...

On the Beeb, here:

BBC

He’s quoted as “....Mr Musk also said he sent the tweet while driving in a Tesla Model S....”

Not “.....a passenger in....”, or “...being driven...”

Isn’t that illegal?

Not necessarily - the laws regarding cell phone use and texting while driving vary dramatically across the US. So basically it depends on where he was.
Still not a very good idea...

Whoops

I was right, Musk has really stepped in it. SEC is suing him for fraud
https://www.space.com/41962-sec-suin...usk-tesla.html
"Musk's statements, disseminated via Twitter, falsely indicated that, should he so choose, it was virtually certain that he could take Tesla private at a purchase price that reflected a substantial premium over Tesla stock's then-current share price, that funding for this multibillion-dollar transaction had been secured and that the only contingency was a shareholder vote," SEC officials stated in the lawsuit, which you can read here.
Not to mention, several individuals are suing Musk because of losses due to his dumb-ass tweet.
He might not be a Billionaire much longer...

Is this where we find out that he had an unhappy upbringing and has turned to non-prescription pharmaceuticals to ease the pain?
Maybe how it ties in with his "pedo guy" statements?

Seriously though, his actions seem to be becoming more and more erratic.
I hope his friends are keeping an eye on him.

Fortyfive percent of all cars sold in Norway in September were of the hairblower variety, Tesla was the number one seller, with nearly twice as many as number two, Nissan.
