You'd have to have stupendously capable AIs in charge of every car on the road - and at the current state of the art that simply isn't possible.

It's much the same with aircraft; in theory, an Airbus can take off and land autonomously, given its sophisticated avionics, and I suppose an air traffic controller could even take remote control of it...but to the best of my knowledge this has never been done with passengers aboard. Nor should it be.

Remember the Hudson crash? Didn't the autopilot refuse the water landing option? Okay, it had to, since it couldn't be expected to handle a non-solid surface - after all it's expecting to detect tarmac or concrete under the aircraft. It couldn't "know" that a water landing would be the safer option under the prevailing circumstances; only Chesley Sullenberger could know that. State-of-the-art tech and software...yet it was a human who saved the day. Left to the AP they would likely have all died. Human skill and judgement pulled it off.

There's an even earlier precedent: Apollo 11. The AP would've brought the Lunar Module right down onto a stonking great rock just where the projected landing coordinates were, despite all NASA's careful planning and surveying. Instead of letting it destroy the LM, killing the crew and likely the entire Apollo program, Neil Armstrong overrode the damn thing and brought Eagle to a safe landing using, again, human virtuosity and experience that no computer system, then or now or in the foreseeable future, could possibly match.

Such auto-driving systems are possible, but they are not ready yet and won't be for several years, I reckon.


Not one of your examples represents AI in any way, shape or form.

Re: Uber Halts Autonomous Car Tests After Fatal Crash in Arizona

In the video she's only visible in the healights at the last moment, but clearly this is a multi lane carriageway and she's already on the road and not moving that fast. The cars other sensors such as sonar, radar and ifra-red, that don't relay on lighting, should have picked her up from quite a distance.

That video gives me anxiety, imagine seeing that whilst driving.

But yeah I think Uber will be looking as to why the radar didn't pick her up.

Re: Uber Halts Autonomous Car Tests After Fatal Crash in Arizona

For the life of me I can't understand why anyone would trust a computer to drive their car.

It's not as if these computers are multi million dollar machines that can accurately plot a course to Pluto are they.

Hands up everyone who has experienced a computer glitch in the last 6 months (Windows 10 users are exempt )

True . . . but they were the only ones up there (as far as we know), and not in 3 lanes of traffic.

It certainly puts todays Sat Nav to shame though

There are plenty(allegedly) of washing machines in space. Astronauts have to keep themselves clean.

The laundromat is the new space station, didn't you know?

You don't. On the contrary, Nasa frequently use old technology as they know it's reliable. If a computer fails on earth, you can send an engineer and they will be there within a few hours. It's not quite so easy if the the computer is in orbit, or halfway to mars..

Exactly not one of the cars censors detected her that's a catastrophic failure in my book .

Re: Uber Halts Autonomous Car Tests After Fatal Crash in Arizona

The problem with any sensor is that it can only detect the static situation. They cannot detect a human intent of change in direction and speed of movement. A human might spot somebody approaching the kerb and be aware of the possibility of them stepping out into the road. At what point does an AI system consider that the vehicle has to take action?

A human can make subtle judgements as to whether to take immediate action or a wait and see approach. Doing that they might not get it right each time, but it is better than the all or nothing approach an AI system would have to take.

Re: Uber Halts Autonomous Car Tests After Fatal Crash in Arizona

For autonomous vehicles to work safely it isn't just the technology in the cars there will need to be external infrastructure technology to assist the onboard systems within any vehicle and we haven't even started to consider that much less implement it. Without technology within the road network and pavements in urban areas I'm not sure the vehicles can reach a standard of safety that we'd all consider acceptable. I wish it was a near thing as I'd love the freedom of personal transport again but i think realistically we are a decade or two away from it.

This ^^

There's a LOT more to driving a car than simply controlling the vehicle

Re: Uber Halts Autonomous Car Tests After Fatal Crash in Arizona

Like extending courtesy to other motorists and allowing them a right of way when non exists. Stopping to allow a pedestrian to cross in-front. So many things that are human nature and very difficult to get a machine to do. When was the last time your computer thanked you for something?
