It still strikes me why so many people are still against a future with self driving cars. Sure, people throughout history are scared of change & new tech. But if you look at this video and compare the amount of stuff the camera catches AND processes, with the things you are seeing & processing, it's really hard for me to see me being better at it than a computer. The reality of driving (as a human) is that most of it…

Show me a self-driving car functioning in the middle of a blizzard and we can start talking. Southern California and the weather it experiences is a poor representation of what is required for self-driving to replace humans.

I was thinking the same thing. I would think they thought to write in some traction detection, however I've never seen a demonstration of the like. They need to test cars in the heart of MN during the winter; when you can't see the lines on the road, and sometimes the car in front of you.

Much faster than a human would react. Acutely focused humans generally take at least 1 second to hit the brakes in an emergency. Longer if distracted or tired[1]. [1]: https://www.researchgate.net/publication/233039156_Brake_Rea...

Braking is slowed by the limitations of nerve conduction down to the legs. You can swerve away from danger with faster reaction time.

The same nerve conduction latency exists for your arms. The computer will beat you every time.

It's a shorter distance.

> it's really hard for me to see me being better at it than a computer There's a big difference between seeing and interpreting. The car sees literally everything and can maybe identify most things, but a pedestrian window shopping across the street isn't really that interesting and neither is a bollard. As humans, we filter out the unimportant stuff to focus on the important stuff. We can also pickup on subtle clues…

you think the average driver is aware of other people's posture and eye contact while driving?

There's no evidence that computers are any better at driving than humans, and there is no evidence that this generation of machine learning will be able to tackle this problem sufficiently. All signs point to driving requiring an understanding of what's going on around you, which this generation of ML does not provide. On the other hand, there is a lot of hype and promises being made without the results to back them…

There is some evidence. For instance, Tesla drivers report the car stopping before they can perceive an accident about to take place. An example is the first ten seconds of this video https://www.youtube.com/watch?v=APnN2mClkmk These vehicles have a superior sensor system to us. Our processing is better but sometimes their superior sensors are better.

Here are the superior sensors steering the car straight into a paper box:

It's even fricking speeding up!

I would much rather we invest billions into existing public transit solutions as a community. A light weight electric train doesn't need advanced LIDAR + AI to navigate, it can transport 100x people than a single car.

Well, that depends on what problem you're solving. Self-driving vehicles aren't solving mass transportation. They're solving ubiquitous personal transportation. They may also solve mass transport by being cheap, ubiquitous, and by performing an end-run around the piles of local regulation that restrict mass transit.

Density + mass transport is the solution to the problem of ubiquitous personal transportation.

I like these videos, but I'd really like to see one in snowy conditions, or other less-than-ideal road scenarios. I think there's a lot more to observe and learn from in those conditions than in bright, sunny days, in well maintained streets.

I'd love to see a Tesla on auto pilot on a Vietnamese 'freeway'... buffalo crossing street while 3 people are driving directly at you on your side of the road, in the wrong direction, while 8 people are crossing the street laterally from both sides (2 of them are drunk), while one person is merging without looking and also dodging a wheel eating pothole and a truck driven by a meth addict, is about to rear end you.

Actually, sounds like it wouldn’t be tough for a Tesla to drive safer than the human drivers on that road ;)

Isn't that asking for too much? Most humans can't drive safely in blizzards. And unlike self-driving cars, many humans are overconfident in their abilities. If a self-driving car recognizes dangerous conditions (poor visibility, malfunctioning sensors, etc), it can simply stop. It seems as long as these machines are safer on average than humans, they're worth deploying.

Really? By your logic Minnesota, Iowa, North Dakota, South Dakota, Colorado, Montana, Idaho, Wisconsin, etc. should shut down for the winter?

Businesses don't shut down just because the forecast says it might snow. Plows can't get out fast enough to clear the road to a point the lines would be readable/visible for a self-driving car. Humans may not be perfect but we find a way to get home in the snow without the massive casualties you're implying should be happening.

Isn’t it enough if it recognises the limits of its own capability and safely asks you to take over?

Lol. This is the kind of comment that I don't expect to see in hackernews, but then again it's about Tesla, so all reasonableness goes out the window.

> if you look at this video and compare the amount of stuff the camera catches AND processes, with the things you are seeing & processing, it's really hard for me to see me being better at it than a computer.

Such a handwavy argument is worth exactly squat. What does this mean? Brains are hugely complicated machines which we barely understand in any reasonable detail. You see a handful of lines and text across the screen and it's sufficient to make you go ":o"? Enough to conclude it must be better than a brain?

So far I only see a world of promises and predictions of "self-driving cars are 5 years away", but no real tangible hard evidence that self-driving cars are better than humans. Point me to that, not to a fancy video, before we can have a discussion.
