My 2015 S70D (AP1 presumably) does start complaining if it thinks I'm about to collide with a stationary vehicle. Whether it would actually stop the car is not something I have had the nerve to test. Perhaps I should find a deserted car park and put out some cardboard boxes and see what happens. The problem is that cardboard doesn't reflect radar well.
Could you wrap the cardboard in aluminum foil?
NTSB: • At 8 seconds prior to the crash, the Tesla was following a lead vehicle and was traveling about 65 mph. • At 7 seconds prior to the crash, the Tesla began a left steering movement while following a lead vehicle. • At 4 seconds prior to the crash, the Tesla was no longer following a lead vehicle. • At 3 seconds prior to the crash and up to the time of impact with the crash attenuator, the Tesla’s speed increas…
As a side note, I find the lane markings in the US confusing. The "gore sections" in Europe are filled with stripes, so there is really no way to mistake them for a lane.
"Unless the road marking is 105% perfect, it's never the fault of the autopilot, but look, autonomous driving!" is just pure marketing, without any substance to back it.

>Cars have been dependent on software for a long time (literally decades). This isn't something new. Even combustion engine cars have had software inside of them that controls the operation of the engine, and this software is vigorously tested for safety issues (because most car manufacturers understand a fault with such software could result in someone's death). Tesla seems to be the only major car manufacturer that…
This comparison just sold me on how morally wrong it is what Tesla is doing. Intentionally misleading and marketing to customers a feature called Autopilot that is only a marginal improvement on what other cars already offer. What if Volvo started calling their (clearly not independent) feature Autopilot and saying it was the future of hands-free driving? Seems inexcusable.

Machine vision is perfectly capable of detecting these barriers, as well as LIDAR. The fault here isn’t with road design. The fault here is with Tesla shipping Autopilot without any support for stationary objects, AND their delusional and (should be criminally reckless) decision to not use LIDARs. A car without ABS or power braking is not legal to be sold today. We need to apply those standards here: anything more th…
I think they rely (more) on radar now since the "I can't see a white truck" incident. The camera is useless if the sun is shining against it, the radar will still work but be useless for stationary objects. I have no idea how Tesla intends to solve this "small" issue.

So human drivers wouldn't crash here? Or a good, attentive, best-case human driver wouldn't crash here? Because those are not the same set, and it seems the former set has crashed into this particular barrier multiple times. I don't think it's acceptible that a vehicle with adaptive cruise, lane keeping, and emergency braking would hit this barrier without any mitigating braking or action, but the actual state of dri…
> So human drivers wouldn't crash here? Or a good, attentive, best-case human driver wouldn't crash here? I'd argue that a Reasonable Person [1] wouldn't crash here. [1] https://en.wikipedia.org/wiki/Reasonable_person
However I also think that the roads are currently occupied by many people who fall below that standard.
Should a car with assistive technologies only be a success if it is as good as a reasonable person, or if it is better than a typical person?
Obviously the former is prefereable to the latter, but people seem much more content with the idea of driving themselves into walls (or another typical person on the road might crash into them and cause that outcome) than with the idea that a computer might do that same.
See also fear of flying vs driving even though flying is demonstrably safer, but feels much more out of the hands of the flyer.

Tesla reminds you to pay attention and keep your hands on the wheel every time you engage Autopilot. It's one of very few legal disclaimers they show you all the time on the screen, and don't give you any way of turning it off.
And we all know how assiduously people pay attention to messages that flash up on screen.
I am continually surprised by how little emphasis there is on personal responsibility when this community discusses an L2 system such as Autopilot. According to both the law and the operating manual, the driver is in control at all times. Tesla warns you of this every time you turn it on. Yes, there are enough bad drivers out there that Tesla is wise to implement habit-forming nags; but drivers also need to take responsibility for how they use (and abuse) these systems. Nobody would pass the buck to cruise control for a driver who set it to 65 and then plowed into something in a moment of distraction. All due respect to the victim here -- and I feel absolutely terrible for him and his family -- but if you are paying attention and looking at the road ahead of you, there is no situation where you accelerate for three full seconds into a concrete barrier at 70MPH -- not with Autopilot, and not without it.

I think the issue is, if you read https://news.ycombinator.com/item?id=17256900 is that Autopilot is not better than humans.
I did, unimpressive, he doesn't have any relevant data. My reply to the post though: Obviously someone shaping stats to their own biases. They want to compare Tesla and Mercedes Benz crash rates because they are in a similar price range? Mind you he has no data on automated driving crashes. Ridiculous and short-sighted, the goal (IMO) is for all cars to be automated. And he assumes that just because lidar is expensiv…

SICK LMS 2xx. Weakest link was the java microcontrollers we had to use because we were majority funded by SUN. My favorite part was the old elevator relays we found in a junkyard and used for a bunch of the control system. You could hear the car 'thinking' and know what it was about to do.
I'm involved in a project using the LMS5xx.. but on a PLC, so I envy your Java microcontroller! Have you seen SICK's new MRS 6000? Range of 200 m, and 15 degrees vertical (15 degrees)! Pricing is similar to LMS5xx.
