My Cybertruck rear ended a Silverado. No Collision Avoidance Assist

[jcktrb]

The Silverado has more visible damage but the Cybertruck will probably cost a lot more to repair.

Start at the 50 second mark unless you enjoy watching 110 traffic.

Unfortunately no alert from the collision avoidance, neither audible nor emergency breaking. Maybe my speed was too low?

I don't think the collision detection would have worked in the situation where you were crossing the line intensionally, at that speed, the system probably thought you knew what you were doing. Just an odd situation for it to detect.

Now that I think of it, about a month ago as I was doing a U-Turn at a light, the car in front of me which was also doing a U-Turn was pretty slow to do so, and suddenly collision avoidance slammed on the breaks and sounded the alert. Caught me & the car behind me completely by surprise because we were all just rolling to that U-turn at less than 10mph so it was a very unnecessary overreaction.

The takeaway for me is the collision avoidance is hit or miss (ha!) on the Cybertruck. I've been driving Teslas since 2017 and I don't recall the behavior being as inconsistent on the Model S, 3 or Y.

That is strange, the CT probably just needs more data. There are 4.9 million + Tesla cars on the road, sending back training data to Tesla. Only <20k CTs on the road. Tesla just needs more collisions to know how to train the data. So we just need more people not paying attention, driving there CTs, and it'll get better.

Edit: Updated total number of Teslas, read stats wrong off quick google search. https://backlinko.com/tesla-stats#

Glad to be part of the data set

I'm sorry you're having to deal with this. Accidents happen and they are a royal pain in the ass.

To me it's not clear what safety features are enabled in the CT yet. This seems like something it should have intervened on but clearly it didn't.

What are the settings for your forward collision warning? Are you driving manually or with cruise control on?

Taking out the ICE cars one at a time. Sucks for your accident didn’t see any reason for dude to stop that hard was a whole lotta room ahead for him. I set my warning to super early but can’t recall if it detects in a lane change like that. Now if someone is turning in front of me it gets annoying quickly lol.

There was another car in front changing lanes and stop in both lanes.

Ah yea didn’t see that the first time.

From Tesla on the Model 3:

https://www.tesla.com/ownersmanual/model3/en_us/GUID-8EA7EF10-7D27-42AC-A31A-96BCE5BC0A85.html

Automatic Emergency Braking operates only when driving between approximately 3 mph (5 km/h) and 124 mph (200 km/h).

Automatic Emergency Braking does not apply the brakes, or stops applying the brakes, when:

• You turn the steering wheel sharply.
• You press and release the brake pedal while Automatic Emergency Braking is applying the brakes.
• You accelerate hard while Automatic Emergency Braking is applying the brakes.
• The vehicle, motorcycle, bicycle, or pedestrian is no longer detected in the front or rear of the vehicle.

I think on the bullet points from Tesla one has at least one listed. Questionable on the speed. I don't think FSD would have tried the move the OP did. Bummer.

Edit add: I have had one AEB on the truck. Check out alerts. They will be listed with time.

I don't think Tesla is spending any resources to speak of on the non-FSD stack. AFAIK, basic TACC, Autosteer, and Collision Avoidance Assist is still hard-coded (not ML). I'm sure someone will correctly soon enough if I am wrong. ;-)

Warning was set to early and emergency breaking is on. I’ve tested it shortly after by tapping the accelerator a bit as I was approaching a stopped vehicle and it did sound the alert.

I was driving.

I’m definitely treating it more carefully now than the other Teslas.

Did you test with the wheels steering sharply to left or right?

I haven’t yet. I’ll try it when I have the opportunity.

What’s interesting is that it did turn the hazards on right away. I thought that would only happen in the event of airbag deployment.

A more obvious question is why didn't you hit the brake when you saw the truck right in front of you stop?

And if you didn't see the truck stop, why were you following a truck so closely that you weren't paying attention to?
