Tesla driver tests the autopilot.

Decides to vacate the driver's seat and assume everything goes to plan.

One of the comments says the men must've somehow bypassed the safety features where there's supposed to be a person in the driver's seat touching the steering wheel.

The airbags need sensors to show there's someone driving but there's no sensor in the seat apparently.

That seems risky.

What's the point of a self-drive car if you have to be holding the steering wheel? You might as well drive it.

Agaliarept - 19 Apr 2021 11:13:28 (#6 of 25)

I assume this feature is/was designed as the testing was being done on public roads.

Probably isn't the intended end point.

Burnt for four hours. Had to ring Tesla and ask how to put it out.

All the Tesla fans are yelling:

"ICE cars burst into flames every day and you don't report on them!!"

Probably isn't the intended end point.

The point where it's properly useful would be where it's as safe or safer than a human driver. At the moment, it's in the unhelpful middle ground where it'll make a driver inattentive by working most of the time, but still create situations that require them to take over.

(And it might never reach that end point....)

Once lithium batteries start burning I don't think much will put them out. Water certainly won't, that's just a dense oxygen source as far as lithium's concerned.

Edit: Google says dry powder works as lithium batteries don't contain metallic lithium

Agree but you probably should've said 'dangerous middle ground' rather than 'unhelpful' :)

Saves on cremation.

I don't much fancy being trapped in a burning car that takes four hours to extinguish.

How does a lithium battery fire compare with a petrol fire in terms of

a) unpleasantness of being in one and

b) likelihood of occuring in a given collision?

solomongursky - 19 Apr 2021 13:26:44 (#14 of 25)

They hit the tree pretty hard and may have lost interest in proceedings.

Petrol will make a big bang

Diesel's safest.

Agaliarept - 19 Apr 2021 13:41:08 (#16 of 25)

There are plenty of videos online of people surviving being burned inside a petrol car. I assume it doesn't burn hot enough to kill you very quickly.

I don't think any burning vehicle is preferable.

:(

bossab2 - 19 Apr 2021 13:44:56 (#17 of 25)

Like I said, diesel is safest.

It won't explode.

FleurDuMal - 19 Apr 2021 13:51:20 (#18 of 25)

Diesel is certainly non-explosive. A friend of mine once said you could drop a lighted match into a bucket of diesel and it wouldn't ignite (I trusted his statement; I didn't test it).

Lithium is a bastard, as each battery unit will set off the next. Richard Hammond had a crash in an electric car (he seems to be testing crashes in all types of vehicle) and the resulting fire went on for three days.

Tenesmus - 19 Apr 2021 13:52:19 (#19 of 25)

What gases are given off by burning lithium batteries?

SinnerBoy - 22 Apr 2021 06:49:17 (#20 of 25)

No sensor in the seat? My last three cars have had seatbelt sensors. You can't even put a two kilo bag of shopping on the passenger seat - it starts pinging.

As for gases, hydrofluoric acid, according to Google.
