Based what I learned about Uber their self driving cars probably run on NodeJS. I'm only half joking.

I don't actually know what a self driving car should run on, I would want to make it in Erlang or Rust but - what do you think a self driving car should be running on?

Amen. Uber's fatal accident rate is now 50x that of sober human driver's. At their current rate of driving, they can't have a _lower_ rate until 2028! Inexcusable failure of their technology to prevent a human death in the most basic collision avoidance scenario.

What is it compared to human drivers in general? That seems to be the fair comparison as "computer will never be drunk/tired/distracted" is usually cited as one of the benefits of computer-driven vehicles.

If you want to be legally allowed on the road, I think your benchmark has to be other drivers that are legally allowed on the road.

I don't know much about the logic used in self-driving cars - but I do wonder how they will handle roundabouts. We have a lot of them here (Australia) and you have to give way to a car that is approaching or entering the roundabout on your right - which often is opposite you. How will a self-driving car cope with detecting a vehicle behind the concrete barrier of a roundabout?

No, the roundabout rule is that a vehicle entering a roundabout must give way to any vehicle already on the roundabout, or a tram that is entering or approaching the roundabout. See the Australian Road Rules, Part 9: https://www.pcc.gov.au/uniform/Australian-Road-Rules-19March... If you are approaching the roundabout and someone enters it from your left before you get there, you have to give way to them .

Isn't this what the original comment is saying though? Considering the cars are driving on the left-hand side of the road, cars in the roundabout are approaching from the right with respect to the vehicle, not the left. Or am I misunderstanding something unique for roundabouts in Australia? The way you describe it seems opposite of intuition that vehicles already within the roundabout do not have right of way.

Several comments here making comparisons to human drivers. As if autonomous cars are ok so long as they are at or below parity with humans. This is statistically true but a complete misunderstanding of human nature. Human risk tolerance varies drastically depending on control/participation. What is the acceptable casualty rate of elevators?

On top of that, I think it is absolutely rational to expect autonomous cars to perform at the current state of the art. We tolerate certain kinds of bad human drivers, like beginners, because there is hardly an alternative. A self-driving car with the driving skills of a beginner would be completely unacceptable if the state of the art has skills comparable to, say, somebody with a few years of experience.

Earlier quoted context omitted.

I drove down a main road here in Chandler, Arizona yesterday and saw three in five minutes. Based on all my experiences on the road with them in the last few months I’d say the chances of them having an incident similar to Uber are much less.

I actually trust the waymo cars more than regular ones now when I'm on my bicycle or motorcycle. Granted they are absurdly "cautious drivers" and can be mildly annoying to be stuck behind in a car.

This is the thing that makes me most excited about autonomous vehicles.

The original comment says "you have to give way to a car that is approaching or entering the roundabout on your right", whereas the rule is that you have to give way to all cars already on the roundabout, without regard to whether they approached from your right or left. If they got into the roundabout before you got there, you have to give way.

Some kind of realtime system. A GC pause of 200ms in a car could easily cause a crash.

Sadly, I fear it may actually be written in C++.
