Default Auto Braking

According to NTSB most automakers including GM are committed to adding standard automatic emergency to most vehicles by fall 2022.

I'm hoping that this shows up in higher level models of C8, and also hope that it includes the related adaptive cruise control and Supercruise system, the best automatic driving available--currently on Cadillacs and being rolled out on other cars.

Corvettes are high performance cars but also upscale, near-luxury vehicles.

Does anyone have any information about GM plans for this? It might cause me to trade my C7 on a C8 (or C9).

I love adaptive cruise control.

I can't stand the emergency braking, All the times it has come on were false positives. Not a fan.

We've got adaptive cruise on both my wife's Cherokee and my Challenger. It's a nice feature.

2020 Cherokee has AEB and has never showed a false positive in more than a year of driving.

Challenger has front collision warning (not as advanced as AEB), and in the one case where that might have been useful it didn't give a warning.

I assume the tech will get better over time.

I turned the nannies off in my S-600.

I dislike the car auto-braking when I get (what it thinks) is too close to another car.
I dislike the auto steering
I really dislike it preventing me from changing lanes without a blinker on.

I can give you completely valid scenarios in each of the above cases where i was trying to "drive correctly" and the nannies are trying to make the car do otherwise.

AEB will result in fewer rear end collisions by the car equipped with it and more rear end collisions to the car equipped with it when the AEB slams on the brakes when noone is expecting it, like when the car ahead is turning right and clearly will be out of the way when you get there but the AEB sensors don't think so. I'm glad I got on the gas quickly in my 2019 Forester when that happened to me at 40 MPH. AEB is good for times you are not paying attention (20+ years since I've had an accident, rear ended the guy ahead at 5 MPH).

Our 2018 Accord thinks all those tar crack seal strips are lane departure.

I love the adaptive cruise control on both those vehicles.

I find auto braking somewhat aggressive. Many times it starts to brake unnecessarily where I, as a thinking driver, would not brake.

Adding all that unnecessary crap to a Corvette will not make it better. It will turn it into a family car. If you want all of those nannies, get a Cadillac and let the engineers concentrate on speed and handling.

If it’s required by 2022, then I would assume it would be standard on all trim levels

I am in favor of having these systems as long as false activations don't happen and cause problems... I also suspect the kid that rear ended me in my Tacoma in a Wegmans parking lot a couple months ago wished he had it. But I am Curious... do you have any intersections with dual turn lanes in both directions? I wonder how these AEB systems handle those when the oncoming cars look like they are about to hit you head on until they turn off at the last second with very little separation? I hope they can tune that situation out or one might get rear ended by the car behind you in the turn lane.

Rented a car with "Adaptive Cruise Control." Didn't know what is was at first. Was on a divided highway without much traffic and had to switch lanes when coming up on another car as the silly thing shut off cruise control well before I would have changed lanes to pass! BUT I wish everyone had both to prevent the AH that drive with their cell phones activated and like Pavlov's dogs have a trained conditioned repose they can't help themselves and have to look and see who sent that foolish text message..

Had a young girl killed at an intersection on a two lane rural road that crosses 4 lane divided highway not far from where I live. According the the police, they believe she was looking at her phone when the very short green light in that direction turned red. She looked down for a few seconds at her phone and the light turned red as she drove through. A log truck, who could not stop, came though his green light and hit her car. They said they see it all the time.

Yep wish ever other driver had and used both or better, do what I do! I have my iPhone set to NOT receive calls or foolish Text message beeps when moving. I also never set up Bluetooth in the Vette so I would not be tempted. Use HUD and my "TV Mirror" to keep track of all cars around me all the time,. Do the best I can to maintain my 61 year driving record of not having an accident with another car! NOT EASY TODAY!

YEP, SOME FOLKS, LIKE PAVLOV'S DOGS, HAVE A TRAINED CONDITIONED RESPONSE TO A CELL PHONE BEEP. THEY CAN'T HELP THEMSELVES.

The only thing I can add to this thread is that your post reminded me of a cover band I was in during college, we named ourselves Conditioned Response after Pavlov’s dogs!

I like the nannies on the MBs but would turn them off on the C8 if they were there.

Can the AEB be turned on and off? I hope so, ‘cause that would be a real problem on the track if you come up fast behind another car.

I also see a problem with the turn lanes, as another poster noted, especially double and triple turn lanes.

Both our 2018 Honda and 2019 Subaru have these "smart" features. There are several double cross turning lanes here and both cars have dealt with the oncoming traffic fine. I frequently am in the right most turn lane at one of those intersections.

That said, our Honda often confuses a brick block mail box at a minor bend on the residential street below us with an in-road obstruction and flashes the big "brake" warning light, fortunately it hasn't done AEB there in this 25 MPH zone.

The Subaru used to allow me to shut off the beeps when on ACC but Subaru did an "update" and now it can only be turned down to a quieter beep. Both cars have easily adjustable distance follow on the ACC.

I would bet GM will add more safety features as the C8 moves forward. Would not be surprised with them adding the AEB, adaptive cruise, etc in the 2022 or 2023 model year.

I have a Buick Encore GX that has all of the more advanced features as on my C8 (electric mirror, cross traffic alert, electronic brakes, etc) with many of the same service bulletins and recalls. The Buick has emergency braking and adaptive cruise which I would a have loved in my C8. Adaptive cruise is simply fun to play with, and as far as emergency braking with pedestrian ability, all you would need is for a kid to run out between two cars and maybe having some protection would prevent death, life long injury, and a depletion of your finances. I'm assuming on a C8 there would be a track mode that turns all the nannys off. I wish my Buick had automatic stop on reverse - something most cars will soon have - if I did I would not have had to replace a $4,000 tailgate. The side mirrors and lane change warning on the C8 seems to work, but on the Buick it's not worth anything as it does not warn right - very irritating. Both cars get about 20MPG in teh city and 30MPG on the highway - the Buick has three cylinders!

I usually keep my phone in my pocket and answer text messages using Siri to read them aloud.
The C8 has a pretty clever interior where the wireless charger is behind your elbow and added wireless Carplay to encourage having you use a voice command to get text read to you.

Totally agree with you that both these features are useful (and, in my view, should have been added at least as an option for the 2021 MY). I considered waiting for 2022, but decided to proceed with a 2021 because there was no certainty that they would actually appear in the 2022 model. The argument that true sports cars shouldn't have those features rings hollow when you realize that they are available on a slew of performance cars (including the Porsche 911). Moreover, if they can be turned off, why should anyone care?

Auto braking I've used in a rented Camry in LV a year ago. The car would brake way too soon ... meant for the Camry crowd of Nervous Nellies.
The only phone I use is in a place where I change costumes known as a phone booth. Hands free phones should be made into a standard mandatory way of communicating in a car.
Anyone using a phone otherwise while driving should have a mandated ejection seat activated and the car lifted off the road by helicopter.
