Featured Safest SUV Ever Tested by NHTSA

I should clarify two things:

First, although I haven't read the "official" report, I have read several other reports on the event and subsequent investigation, and yes, they seem to make a plausible case that, sadly, the driver should have had no problem avoiding the accident.

Second, I'm asking about why radar didn't trigger an emergency brake much more from an engineering-design perspective than from a lawyeristic whom-to-blame perspective.

The answer is the software at the time required seeing something visually on the cameras to confirm the object on the radar. IMHO this was a design defect, one of many in a new system. It expected the driver would see something and brake if the camera was wrong, and didn't want to brake if the driver didn't want to with no visual confirmation.

They quickly changed this software after learning about this accident.
They also made changes to the hardware for new cars. They also have the software brake from the radar, even if the driver doesn't have autopilot on.

As I recall, emergency braking wasn't really part of AutoPilot 1 itself, but was a largely separate module purchased from MobilEye, and it's much more tightly integrated under AutoPilot 2.

In any case, it was not active during the crash. It was before end of 2016 in autopilot 1 based hardware cars.

Autopilot 2 cars just got AEB in April, and it does not yet work at higher speeds. This uses a better better and longer range camera, longer range radar, and sonar, as well as nvidia instead of mobileye chips. Tesla is involved in a lawsuit about allowing a driver to override AEB. Its kind of crazy. Here is about the AEB rollout to autopilot 2 hardware.

Send the audio alert and after 5-10 seconds, start decrementing the cruise control speed and move to the right. Call it the 'dead man' maneuver.

Even slowing the vehicle down by about 20% should be enough to make someone grab the wheel. Also, escalating volume and shrillness of the warning sounds would help.

 

tesla on dos?

 

Berkshire Hathaway owns Nebraska Furniture Mart which is one of the biggest, if not the biggest, furniture company in the world. Their in house sales software is all on old-school green and black DOS.

 

probably better than windows 10.

NOTE: I've owned MacIntosh computers since the 128k. I had one DOS luggable that I used whenever my blood pressure was too low. Now I have a virtual PC with a copy of Windows XP to support TechStream.

i hope tesla didn't make a mistake getting rid of the bad apple.

 

I've never bought a PC for my own use, but use them at work - both Linux and Winders.

I did Atari STs for a few years in the mid-late 80s, but all Macs since an SE30.

who was going the wrong way? we just had one last night.

 

i've actually experienced that at least once on the highway. it's a shocking sight, just the car coming the wrong way. never seen an accident, thankfully.

 

A good reminder that any direct accident above 45mph is going to be deadly 9 out of 10 times.
