You shall not pass!

Dude uses smoke screen and spikes to try and avoid police

I think his engine was just blown, looked like water vapor to me. I worked in a garage once and the owner had me drive an audi around to burn off the oil that had collected in the exhaust system. At full throttle it would have blanketed a two lane road completely for 200+ yards.

Tesla Model S driver sleeping at the wheel on Autopilot

I'm not sure you understand what machine learning is. As I said, the trigger for your child.runsInFront() is based on numerical inputs from sensors that is fed into a formula with certain parameters and coefficients. This has been optimized from many hours of driving data but ultimately it's not able to predict novel events as it can only optimize off existing data. There is a base level of error from bias-variance tradeoff to this model that you cannot avoid. It's not simply a matter of logging enough hours of driving. If that base error level is not low enough, then autonomous cars may never be deemed reliable to be unsupervised.

See: https://en.wikipedia.org/wiki/Bias-variance_tradeoff
Or specifically: http://scott.fortmann-roe.com/docs/docs/BiasVariance/biasvariance.png

It's the same reason that a stock market simulator using the same method (but different inputs) is not accurate. The difference would be that while 55% correct for the stock market may be sufficiently accurate and useful to be profitable, a driving algorithm needs to be near perfect. It's true that a sensor reaction time to someone braking unexpectedly may be much better than a human's and prevent a crash, so yes in certain cases autonomous driving will be safer but because of exceptional cases, but it may never be truly hands-off and you may always need to be ready to intervene, just like how Tesla works today (and why on a regulatory level it passed muster).

The combination of Google hyping its project and poor understanding of math or machine learning is why news reports just parrot Google's reliability numbers. Tesla also, has managed to convince many people that it already offers autonomous driving, but the auto-steer / cruise and changing lanes tech has existed for around a decade. Volvo, Mercedes and Audi all have similar features. There is a tendency to treat this technology as magical or inevitable when there are some unavoidable limitations behind it that may never be surmounted.

Volkswagen - Words of the World --- history of the VW

Payback says...

It's interesting to note the initial class action lawsuit against VW and Audi failed because the lawyer for the plaintiffs mentioned VW's founder in his opening arguments and the judge ruled against him under Godwin's Law.

A bloke from Audi spoke to us during a class on model driven software development in '07 and the entertainment system was #2 on his list of opportunities for software developers, right after driving assistants. When a friend of mine asked him if it would be air-gapped from the rest of the system, he was quite eager to swipe aside all security concerns.

Makes me wonder if he's still prancing around with his glorious fully-integrated systems...

Greetings Seltar!

I hope this note finds you well. I just came across this video of one of your fellow countrymen having quite some trouble with the voice control on an Audi car, I thought you might get a giggle out of it:

Perhaps you're right and they thought of that...but also perhaps not.
I must admit, I had not taken it being only on Audi's into account.
For jmd: Where I live, in the boondocks of far N Cali., we still have timed lights, and at certain times of day they are timed to force you to stop at (at best) every other block unless you speed like a demon. In order to hit every light green, you would have to either drive double the limit, or less than 1/2. They do this as a speed control measure, even though the limit is 35mph on main street. All that said, I doubt these old style traffic lights would 'talk' to the cars computer, making the whole point moot.
When my car drives itself I'll be far more forgiving of poor drivers, because it will be the car dealing with their mistakes while I just read a book...I can't wait. Until then, I'm a victim of my own limited patience.
I recall in Houston the freeways have a MINIMUM speed limit of 45 (which is ridiculous to anyone who has ever driven in Houston traffic...but I digress). I think minimum limits are good ideas. I think moving violations for people driving slow in the fast/passing lane would do the most to increase the flow of traffic, but that's just me.

I really don't think it would ever tell anyone to drive at 5MPH down main street. The people making this have probably given the system enough thought to take reasonable driving speeds into account.

I also doubt that a significant number of people would follow that sort of instruction. There are a lot of stupid and/or selfish drivers out there but not many who would inconvenience themselves in this manner. (By reputation, Audi drivers aren't often accused of driving too slowly.)

Aren't lights typically timed to help people make them at the speed limit, regardless of how busy the area is (as the speed limit is already accounting for this)? I'm certainly not going to condemn anyone for driving over the speed limit but if other drivers who do stick to the limit are a problem then you shouldn't be driving. Besides, we'll have to get used to keeping to the speed limits when our cars drive themselves.

newtboy said:

OK, you are correct. This tech likely would only direct bad drivers to go 5mph to make the lights on main street (and I say 5mph because some lights are (or at least used to be) timed to make it impossible to 'make the lights' unless you go that slow, this is done intentionally to slow traffic in high traffic/pedestrian areas...it was a worst case scenario but one that happens).
My worry is that many if not most people are inconsiderate enough that if their car directs them to go 5mph, they'll do it without question.
Once the cars drive themselves, if this issue is not taken care of, then it's a bad technology.

@yellowc

Changing your speed by 5 MPH or even 5 KMPH (3 MPH) could be a problem. Changing your speed to 5 MPH, as newtboy said, just seems to be drawing massive, ridiculous assumptions about how this works, as if no one at Audi would realise that this would be terrible.

You don't go anything like as far as him. Lines like "this doesn't excuse your product for not working" still imply an assumption about how effective this is that I didn't get from the video but the video is fairly low on substance.

If you're intending to be dismissive then I disagree but a certain level of cynicism is healthy.
