I'm more than happy to do so considering I put myself inside my own murder machines on a regular basis!!!

The part they talked about with autonomous vehicles being cautious by nature isn't talked about enough though. People want to focus on swerving away from school buses, but when super-cruise becomes common and some 20% of vehicles on the freeway are using it you'll see some real impact on traffic. Right now supercruise vehicles maintain a distance from the vehicle in front of them that is much less than most people drive at in traffic. So a supercruising car will not only be getting constantly passed by manual drivers, but a lot of them will start to slow down traffic because the throughput of a section of freeway will be much less.

I'm not an expert in traffic so maybe this buffer zone will help mitigate traffic jams in some way (where someone fucking up and causing a bunch of people to brake suddenly will ripple through traffic for miles), but it will be interesting.

I have been trying to get a hold of an engineer on the Google self driving team to ask what they are doing about motorcycles lane splitting in California which can bring them within distance of a car that might not be enough buffer.

Anyone know aomeone? Or the same at Tesla I guess?

I wish science would just forget about autonomous cars and create me a teleporter.

The very first thing created after a teleporter is the teleport blocker. We live in a world that relies on doors and walls with physics that assumes you can't warp through them.

Are you talking about motorcycles/cyclists driving between cars in traffic? Assuming yes, I don't know what they specifically do. Or what they do if they are parked and some jackhole comes and stands close to the vehicle.

This presentation might give you some idea of how their processing works though. I was at a much longer Chris Urmson presentation earlier this year and he had some very interesting real world examples where the google car was put into difficult corner cases.

If google cars are programmed for self sacrifice, could you trigger that programming by driving poorly intentionally?

People like Tuco think of fringe cases, people like me think of OPPORTUNITY!

First thing I'll be doing with my google car is to hack it to perform wheelies near schoolbuses.

First thing i'll be doing with my google car is buying a decom school bus, getting my CDL, and driving like a stupid person.

We need some QA up in this bitch.

Yea, I mean I basically ended up with ACC and it's pretty handy, especially the crash avoidance features. It won't swerve because it's not full autopilot even though it does have lane-keeping so it technically could.

That said I have to chuckle when they're so full of themselves they're thinking about whether to sacrifice the consumer to save kids literally, lol.

Actually that 'edge case', if you will, is arguably outside the 3 laws. In the example dilemma, the given facts are that the car A) knows that a bus load of children will die if it does not act and B) can only act by killing its passenger. In this case the car/robot has found itself in circumstances where its direct actions must lead to the death of human beings. The question is then given that information, should the robot do what it is literally instructed by rule 1 (do nothing and cause deaths but not actually kill) or make the best effort to adhere to rule 1 by acknowledging the direct actions will kill and minimizing the deaths? Option A only actually works until you introduce general AI that can understand consequences.

I find it interesting how close you are to programming robots to discriminate in this example. Some human lives are worth more than others. Perhaps the most efficient method would be to classify humans based on their inherent point value. Now we know why SJW consultants have been brought into google recently.

2011, they found the data collection error and science remains in tact. Pretty sure that was posted already years ago.

Gravitational Waves Have Been Detected For The First Time | IFLScience

The Laser Interferometer Gravitational-Wave Observatory (LIGO) in the United States has detected gravitational waves for the first time. This is one of the most important astrophysical observations since the discovery of the Cosmic Microwave Background.

"We have detected gravitational waves. We did it!" said Daivd Reitze, Executive Director of the LIGO Laboratory at the California Institute of Technology, at a press conference announcing the discovery

Gravitational waves are a prediction of Einstein's Theory of General Relativity. According to Einstein, gravity bends space-time, and the more massive an object is, the larger the effect. When massive objects move they create an oscillation in space-time, gravitational waves, a bit like the waves that form in front of a moving ship.

The gravitational waves were observed on September 14, 2015, and they were produced by a pair of merging black holes, one of the few events thought powerful enough to produce gravitational waves that we can detect. The two objects are about 150 kilometers (95 miles) across and merged 1.3 billion years ago. They had similar masses, one weighing 36 times the mass of the Sun and the other 29. The discovery has a statistical significance of 5.1 sigmas, meaning that there's only 1 chance in almost 6 million that the result is a fluke. The results will be published in the journal Physical Review Letters.

It will bring to a head decades of searching by scientists, who have long sought evidence for gravitational waves. They are thought to move through the universe, squeezing and stretching the fabric of space-time, but the oscillations are incredibly small and thus very difficult to detect, requiring incredibly sensitive instrumentation such as LIGO.

"Detecting and measuring gravitational waves is the holy grail of Einstein's theory of General Relativity," said Professor Bob Bingham, a physicist at the Science and Technology Facilities Council at Harwell Campus in the U.K. "This discovery leads the way to look back in time at the creation of the universe, with significant repercussions for ongoing astronomical research."
