You had some commentary about geofencing the feature to highways and teaching Tesla drivers that their system won’t stop for parked cars, but you edited the post, I think.
(I just happened to load the post at the right time I guess..)
Yeah, I underestimated your response time at 4 am
. I originally added:
Maybe Tesla should Geofence it by defaults to highways, and then make drivers take a written test where they have to e.g. write out the words: "I know AutoPilot does not stop for parked cars" a 100 times before the feature will be enabled on all roads again.
But the post got too long.
Answers:
On the geofencing I have no opinion.
But since I’m a “Magic brillance of Musk” dolt, why wouldn’t the thing stop for parked cars?
All of the ones built as safety systems will stop for anything solid that they have a closure rate on. They will have warnings that there are limits to how quickly they can stop, and they’ll likely hit the object, but they don’t flat out say “We’ll hit parked cars...” they say “The system will do its best to stop prior to any collision with another vehicle”.
I think Subaru, as the only example I’m very certain about, gives a “guarantee” that they’ll get stopped with their sensor package from any speed 35 MPH or below, and they don’t say it, but that insinuates they’ll slow at least 35 MPH for any immovable object.
There is no such guarantee. Here is the Subaru Eyesight disclaimer:
"Never drive the car relying solely on the system explained above. The system has been designed to assist the driver in making decisions on the road, and to reduce the chance of accidents or damage. It was not designed to prevent drivers from failing to focus on the road ahead by driving inattentively or carelessly, nor was it designed to provide driving assistance under poor weather or visibility conditions. It was also not designed to prevent collisions from occurring under any conditions. Drivers are responsible for driving safely and shall comply with all traffic rules and regulations regardless of the fact that the car is equipped with the system. Drivers shall ensure that they are driving safely, maintaining a safe distance behind the car in front, paying attention to their surroundings and driving conditions, and applying the brake or other measures to maintain a safe driving distance. When a warning is activated, drivers should pay attention to what is in front of the car and its surroundings, operating the brake pedal and taking other action as necessary. There are limits to the system recognition and control performance, in addition to the outline provided here."
"poor weather or visibility" - I get that. But: "it's not designed to prevent collisions from occurring under any conditions". Mmm. What exactly are those conditions? How does that legal statement help me as a consumer? Tesla just makes it more obvious what those conditions are and what I should watch out for. I prefer to know what they are.
Look, the Subaru Eyesight, Tesla Model S and 3 have essentially identical IIHS Front crash prevention rankings, apart from it being optional for the Subaru and standard for the Tesla:

AEB is not even a thing anymore. Most auto manufacturers use the same equipment from Hitachi, Bosch and MobilEye. (Tesla now has developed their own after their public spat with MobilEye, but the vehicle in question in this crash still has the old MobilEye system). Subaru uses Hitachi. But point is - AEB on all vehicles perform approximately the same and have the same limitations.
The sad fact is that Automatic Emergency Braking on any vehicle is not always going to brake, and one of the conditions it isn't going to brake is if a vehicle is parked on the side of the road while you steer towards that lane (with the intention of steering back before you hit it). It can't - your car will brake all the time while you're just changing lanes around town and will essentially be unusable. If a vehicle however slows down and stop close to you, the radar-based systems will indeed stop for vehicles on the side. But that's a very different case than parked vehicles and won't be an unusable nuisance.
(As an aside, on the famous Uber crash, AEB was disabled).
One cool thing that I give Subaru props for - they enabled rear-AEB before Tesla did. Tesla has autopark which will detect vehicles and obstructions and not drive into them. But autopark is crazy slow - pretty much a gimmick. I prefer parking myself and I just want rear-AEB to look out for pillars that want to run into me. Tesla has all the hardware to do this, they just haven't done it yet.
And I believe their system does NOT apply full ABS braking. The driver can react and mash the brake pedal to the floor and make the stop from speeds above 35 MPH to [unknown limits based upon road and tire conditions].
Same with Tesla. It doesn't slam on the brakes at high speed - it reduces speed by 35 MPH - you have to do the rest to get it down to 0 if you're over 35 MPH to start off with. I assume it's similar with Volvo, BMW, Merc, Lexus etc.
Which if you’re going for geofencing, should be another place manual driving with full auto-stop safety systems for immovable objects should be the norm. But again, I’m not going to give commentary on geofencing. That would lead to commentary on weather hazards and all sorts of other times the system should be disabled, and the list would get to be massive.)
I just meant for AutoPilot mode. Auto Emergency Braking is active all the time (AutoPilot or not), but has limits. If you drive past a bunch of parked cars AEB is not going to help you, so my somewhat out-of-frustration suggestion is to disable AutoPilot on non-highway roads with known parked cars, so drivers will be forced to drive themselves and pay attention to the vehicles around them.
When AEB works properly however, it's a thing of beauty. I've had one case where my car engaged a 2-vehicles-ahead stop like the one that's 45 seconds into this video:
Basically I was following a truck and my car just suddenly stopped and beeped, and I couldn't see why. Two seconds later the truck in front of me also stopped, and moved to another lane. Turned out the car just in front of THEM just got into a fender bender and stopped. I didn't see the accident at all until the truck moved out of the way. The radar bounces under the car in front of you so it can track vehicles ahead of them. Now THAT kind of things I think are very cool. Things that humans can never do impress me more than things that try to approximate humans.
I also had a side-swipe avoidance kick in 2 days ago for a car drifting out of his lane on my right. Also cool, but I would have likely been able to do the same. Still, cool to experience.
