>Or even avoid a pothole. Humans can avoid potholes with one eye. I don't know why you assume LiDAR is a requirement for this.

One eye backed by millions of years of training in depth perception and object recognition... The argument that humans are able to drive with just two cameras and software (brain) is deeply flawed because the brain is highly advanced in areas necessary for driving and Tesla's claim it will replicate that any time soon is absurd. This is why you need additional sensors like LIDAR to alleviate the computational load.

The human brain is a hard AI entity that can think through problems in any generic situation.

In self driving AI you are programming the car to do a specific thing. Sooner or later you will run into a situation in which algorithm will panic and can't do much.

If only the brain would be smart enough to focus on driving instead of distractions...

I know it's popular to bash on Tesla's current challenges with their Autopilot software, but I think it's a bit unfair to expect them to be back in front of the pack just yet. They had their big breakup with MobilEye in, what, September last year? Nine months is pretty quick to go from total reliance on a vendor package to a reasonably functional fully in-house system.

Can you explain the 'back' part of expect them to be back in front of the pack ? As far as I know they've never been in the front of the pack.

Actually, they are and have always been in front of the pack.

You can't really drive in the dark, can you? What if it gets dark for 1 second on a cliffside turn?

It's pretty obvious that a self-driving camera-based software would take advantage of headlights on a car, just like a human does? So it never has to drive in full darkness.

Actually you will need more than a camera input, may be even a sound input.

In darkness it helps if you can hear the vehicles coming close.

You missed the analogy: Darkness is to eyesight as inclement weather/obstacles is to LIDAR

What's the point of that analogy? Darkness can be fixed with lights on the vehicle itself. Inclement weather is entirely outside the control of the vehicle.

>>It will be very interesting to see how self driving systems can cope with these local unwritten bylaws. This is why self driving AI will require Hard AI. India is a perfect test bed for these people to test their algorithms. And for heaven's sake why would you test it in some place like the US. Cars in US are pretty much trains on road any way.

Because that's where the (easy) money is

I get it. They would want to release their cars in US or Europe as their primary markets.

But even in those cases it makes sense to test in India. Why? Sooner or later you will have some situation in the US which may resemble daily traffic conditions in India. Imagine a law and order situation where people are running around without regards to traffic laws. Or some other situation where traffic is being rerouted through a wrong way, In US may be as an exception traffic is being routed through the left lane(being a right lane drive country) etc etc.

For all these situations you will very soon need a test environment that provides you with all situations to test.

Driving a car is currently specialised, as is folding laundry. The opportunity for autonomous vehicles is clear; you can start with replacing the cost of paying every person around the world who drives for a living with profit equivalent to their income. (likely at somewhat less than 100% efficiency, but who cares because of the massive scale?) The next bit would be converting private trips into automated rides; repl…

> replacing the cost of paying every person around the world who drives for a living with profit equivalent to their income That's not how it works, because your competitors will undercut you. Then you will undercut them, and continue the race to the bottom until the natural price is reached.

The efficiency will certainly be a lot less than 100%, and it does seem likely that at least two companies might bring the tech to market within a couple of years of each other. I think whatever the starting price point is, there will probably be so much of a demand/supply gap that the initial price point will hold for a number of years.

You have to be careful how you let people go if you want to attract good talent. There is always a chance of a misfit, and the right thing to do is to part ways as soon either party realizes it, but you want to do this in a way that is not unnecessarily damaging to either party's reputation. Otherwise, good people with a reputation may think twice about working with you.

Reputation is for B players. Chris Lattner can go work for any company in the world that can afford him. A players don't look at company's reputation, they look at things that actually matter.

Exactly, not everyone is interested in playing the pc game. What if they mean exactly what they say: not a good fit. That doesn't mean he is bad at his job.

That's like saying our eyes are useless because we can't see in the dark.

You can't really drive in the dark, can you? What if it gets dark for 1 second on a cliffside turn?

Actually in the dark you often drive as a leap of faith in the state of the road. I.e. with very little visibility on what can come from the side of the road (no light) or after a turn. We shouldn't. But we do.

I will take your self driving car seriously if you can drive it in all conditions in India. Until then its just an attempt to make something that breaks at the next unanticipated exception.

I wouldn't drive in India. And I'm human.

You are only human. Its super human who can drive there.
