You do not want root on your self driving car. Or to put it differently, I don't want to be driving on the same road as you with your rooted self driving car. You can be great sysadmin/coder, tesla guys may be too, but both of you changing random stuff without any communication with each other.. I've seen enough servers.

I am trying to imagine the typical arch Linux enthusiasts modifying the lane detection software on their cars and shudder at the thought.

This is a problem that will very quickly fix itself, as morbid as it sounds...

The location is the end of some tidal flow lanes rejoining the main freeway lanes with an unusual configuration of lane markings and barriers. I drive past the spot all the time and can totally see a computer messing up here.

In other words, "works great if it works, might actively try to kill you at random, there's no clear way of telling when it might try the latter, it's your fault in any case." Yeah, that's very much the safe driving paradise I'm being promised "in two years" for a decade now, by the technooptimists. It's almost as if the technology is at 50%-ready instead of the 90% that marketing types seem to peddle, who would have…

Here is my armchair diagnosis: right before the car veers towards the barrier it drives through a stretch of road where the only visible lane marker is on the left. Then the right lane marker comes into view at about the point where the lane starts to widen out for the lane split. The lines that will become the right and left lane markers of the split left and right lanes respectively are right next to the van in fro…

I don’t know you, sir, but Tesla should hire you!

That's exactly how a lot of commercial aircraft systems work, they have three, if two agree and one disagree then that one is ignored. But it is more complicated than that when you're talking about algorithms and complex systems. If you had three of the same exact system, they'd likely all make the same mistake and thus you'd gain no safety improvement (except actual malfunctions, not logical limitations). I would li…

This has been mentioned a lot of times lately (the auto-braking). When you think about it, you realize there are a million moments during normal driving where you have an obstacle ahead. Other cars, lane dividers like these that you might _have_ to pass by closely, or at least will have your car pointed at it for a few seconds, making tight curves on a walled road, high curbs, buildings that are on the edge of the ro…

My understanding is that auto-braking during autonomous driving doesn’t normally react to stationary objects like barriers. Otherwise it would brake for things like cardboard boxes, plastic bags, and other debris that often makes its way onto the road. But rather, autonomous driving AI puts a lot of trust into its lane guidance.

I feel that’s the problem. Techniques like SVM can provide reasonable definitions of confidence. Reinforcement Learning.. DNN... the mechanisms behind autonomous cars... are they able to do this??

not an expert, but aren't the output nodes thresholded to make a decision? How far you are from the threshold might be interpretable as confidence possibly?

Yep that's exactly what you would do.

However, in practice, this usually is just not a good indicator of confidence. NNs are notoriously overconfident.

Is it really odd that two people could reach the same conclusion when presented with the same video?

Of course not. But it is odd when the top rated comment directly below the video is essentially the armchair theory that was proposed.

I drive a Nissan myself, but from the sounds of it it's about the same. LDW (just warning in my case), FEB + pedestrian/moving object detection, blind spot detection, intelligent/adaptive cruise control. (There's also a lane keeping system option called ProPilot, but I skipped out on that - I don't think I'd trust it in the regular rain anyway) Anyway, my point is these things are common now, and while getting the fu…

I have ProPilot. It's pretty great. In heavy rain it shuts itself off and tells you that it is unavailable in bad weather.

That's great news. ProPilot sounds ideal for dealing with daily stop and go commute without the cost and risk of Tesla

The comment above is saying the split looks like a diamond lane marker indicating an HOV/electric car lane, so the car is centering itself on the diamond. That's a completely different idea from the Reddit comment about the car centering itself between the right and left white lines. My guess is that both inputs contributed to the car "thinking" it was following a lane.

The conclusions are the exact same. The autopilot was trying to center the car between lines.

>My guess is that the autopilot mistook these lines for the diamond lane marker and steered towards them thinking it was centering itself in the lane.

It sees the white line on the left, the white line on the right and thinks its a big lane. Its trying to center the car in the lane.

All the other people on the road are having autopilot forced on them by reckless early adopters.

> by reckless early adopters. That's a pretty important point. We aren't going to ban alcohol are we? Aren't we even trying to allow marijuana consumption? Both of theses put you in dangerous situation on the road, yet we aren't talking about blocking their consumption. It still the responsibility of the adopters, just like it's the responsibility of the drinkers. At least doing it safely actually improve security in…

Not on public roads.
