At least I enjoy what I'm driving.

Auto hold?
On two of my other cars, a CT5 and an F150, there is the Auto Hold feature, which I use every time I drive. In city driving, it is good to be able to let foot pressure off of the brake pedal on long traffic lights. On my C8, there is not this feature and my work around is to pull the parking brake button, and them when it is time to go, just as I start opening the throttle, the brake releases. Isn't this just manually doing what the Auto Hold system does?

I used the autohold on my CT4V Blackwing every day driving through hollywood on my way home from work. Loved it and not sure why the C8 does not have it. Also loved the adaptive cruse control. However, after a few months of driving the C8, I cant say I really miss the autohold, but I still miss the adaptive cruse.

The C8 is already overweight. Adding more goodies doesn't help the already glaring problem.
I'm for pushing the park button and it's available now.

Isn't this just manually doing what the Auto Hold system does?
Now, in case one thinks otherwise - here is the explanation from the manual:
"When the vehicle is stopped on a grade,
Hill Start Assist (HSA) prevents the vehicle
from rolling in an unintended direction during
the transition from brake pedal release to
accelerator pedal apply. The brakes release
when the accelerator pedal is applied. If
the accelerator pedal is not applied within
a few minutes, the Electric Parking Brake will
apply."
From this explanation, you can deduce that what is happening is it applies the regular brakes first, but if sit on the hill too long that way - it does apply the electric parking brake.

My daily driver is an Acura MDX and it has brake hold. I push the auto stop/start button to off and the brake hold button as soon as I fasten my belt every time I drive it. I do miss the brake hold when in the C8 but I think it does have hill hold. Sadly, I sitll have under 700 miles on my car after more than two months of ownership.

The Hill Start Assist feature is not intended to allow the operator to stop pressing the foot brake - rather it "prevents the vehicle from rolling in an unintended direction during the transition from brake pedal release to accelerator pedal apply". On a normal start without active Hill Hold assist, when the driver starts to release brake pedal pressure, the clutch actually starts to engage (see statement below by Josh Holder). If an Auto Hold feature was added for the specific purpose of holding the car still while the operator stopped applying the foot brake, with the gear selector in D, how would the clutch pressure modulation work?
Josh Holder: ".......the clutch engagement is controlled by hydraulic pressure. We apply pressure to the clutches which is how much friction they are applying and how much torque is being used to creep the car forward and that is a function of brake pedal pressure. Its not just on – off, because that would make it very clunky and awkward driving experience. So the more firm you are on the brake pedal, the less clutch pressure we’re applying. As you back off the brake pedal we’ll start applying more clutch pressure so the car’s ready to move like a torque converter automatic transmission even though this is completely different. So it operates the way people expect in automatic drive mode.”

I'll really miss this feature as I move from the SL63 to the GSX. My wife and kids all have this feature in their BMWs and Mercedes s, even though they've chosen not to use it themselves—which I always thought was a bit of a shame! This feature truly adds comfort and convenience to the driving experience. Its absence in the GSX will definitely be noticeable for me.

Funny, my 2025 Honda Civic Hybrid has all that, Auto Hold, Adaptive Cruise Control, Lane Keep Assist, etc.... Do love the Auto Hold.

That's my guess. With the current C8 design, selector in D, as the drive release the brake pedal, the clutch slowly starts to engage so that the car starts to creep forward as it would with an automatic. This happens before any throttle is applied. At that moment, the clutch is actually slipping as the car comes up to speed enough to fully engage without lugging the engine (about 5-7 mph). An auto hold feature, designed specifically to apply brakes automatically so the driver does not have to apply the brake pedal, would complicate this. Would it disable the idle creep feature during auto hold, or would it just hold the car and allow the clutch to slip? I'm not saying that an approach could not be worked out, but it might be a little clunky.
When the hill start assist kicks in, it actually is a little clunky right? You must push the throttle a little harder, and then when the brake releases it starts abruptly. I think a start from auto hold would be the same way.
