Tesla

[Soup DeVille]

How many motorists would look at the sign and say "sweet!"

Did you actually look at any of the "hacked" signs?

[Soup DeVille]

From comments I've seen on other sites, the newer models do that. Only the first models only read signs.

Doesn't Tesla do wi-fi updates?

[Soup DeVille]

If the car is tricked into speeding and is being chased by the law, and the driver is asleep, should there be a provision for the car to recognize the law and pull over?

Just wondering.

on-command shut down is a thing.

I wonder how many owners of GMs continue to pay for their OnStar system.

That's correct, the current models do not read signs. The first models used Mobileye hardware and software. The current models use in house hardware and software. Mobileye has a patent on reading speed limit signs, so that's why the current models don't do it.

So the current models are Only using GPS data then and Not reading the signs?

Yup.

[Soup DeVille]

Yup.

That's just swapping one single point failure system for another.

I'm not paying for any satellite service in new van but it loads the CD information anyway.

At least it can't be modified by vandals.

But but but what happens when a hacker jams GPS signals

[Soup DeVille]

But but but what happens when a hacker jams GPS signals

Which, although unlikely, can and has happened. What's far more likely is to just lose GPS signal- in mountains, or tunnels or in between tall buildings. Or for the road speed limit to be updated and the GPS data not match the signs, or for their to be a problem with the onboard GPS itself.

Seriously, you already know the dangers of a single-point failure system, why are you trying to play like its an invalid concern?

[Laconian]

You can do a pretty good job of dead reckoning with depth sensors and a compass.

Yes, you can; and I assume some sort of system is in place already, but as I learn with Tesla- I don't know. It looks like they do it as fast and as loose as they can get away with.

Pretty much any manufacturer does the most than can get away with but most any normal industry is reigned in by customers, shareholders, advocacy groups, etc. Tesla of course is 99.9% free from such constraints.

My experience is that Autopilot will not adjust the speed once set. I.e. it uses the speed limit from map data to set the speed when you engage cruise control, but it won't change that speed even if the speed limit changes after that. Maybe this has also changed since the early models.

Edit: according to the forums this is because of the low accuracy of the speed limit database. The version that reads signs is more trusted and thus is used to automatically speed up and slow down.

[Soup DeVille]

So its not that they simply went from one methodology to another, but they also removed functionality?

What was the reasoning for leaving Mobileye?

I would assume cost?

I find this hilarious- I'm pretty sure Google maps' database comes from their cars driving around and taking pictures of speed limit signs which get parsed by computers and put into the database.

Cuz the speedlimit always changes in Google maps right where the sign is. No sign= no Google Maps speedlimit.

So yes it depends a lot on how often they drive the car around.

Seems so easy that big groups of people that have lots of employees always everywhere could just keep track. (like gubments)

Humans are a single point failure

[Soup DeVille]

Humans are a single point failure

And can't be redesigned. Machines can.

As would I, but such cost cuttings measures, in a system with so much to prove, seems counterproductive.

Google's map data quality varies tremendously from country to country.

I'm sure. Because of government restrictions partly.

When a machines greatest need is additional programming to deal with humans trying to fuck with it, it's probably already better then humans

[Soup DeVille]

Then and than. There's a difference. Learn it. Believe it.

What concerns me is not whether or not its "better than humans," but whether or not they are making cost cutting moves when there are viable and existing alternatives that are safer.

[Morris Minor]

The fix would be to make governments liable for any speed limit changes not communicated in advance to those that need to know. A single notice to a clearing house of some kind would suffice. 180 days.

That sounds too simple and common-sense. Would never work.

For serious though- think of all the different ways people have solved problems- and we think "why couldn't the government have done that?"...

Not to mention temporary speed limit changes due to road construction or events, etc.  The speed limit on part of I-690 near the NYS Fairgrounds gets reduced to 55 mph starting a week or two before the state fair until a week after.

Tesla was releasing things to the public without validating and pushing unsafe updates out.  Mobileye wasn't cool with it.
