So I have 800 miles on my car now and Hill Assist in the driver's aid has been on the whole time by default.
As I understand it the car senses when you are on a sloped hill and will maintain the brakes for a couple seconds to give you time to move your foot from the brake peddle over to the gas.

Here's my issue: there's a corner market by my house that I drive to often, the parking lot entrance to the street is loped so I take very slow/angled approach.
As my front end has cleared and I'm pulling the car through, 1 rear wheel is just rolling onto the street while the other rear wheel is just coming off the sidewalk transition and every time I get this weird thing happening, feels like 1 wheel just hopped off the curb. Every time. Is this the Hill Start Assist applying the brake?

To state the obvious I'm going to turn it off before my next time through this parking lot to see if there's any change, but wanted to ask what's your experience with this?

I make the same approach into my driveway and never heard your sound. I keep hill assist on since I live in the hills. Nothing like sitting uphill at a light and someone wants to get closer to your bumper to check out the snake. I like zero roll back, good science in that idea. Is your sound gear transition in the Differential (gear driven posi)? Interested in Hill assist off does anything.

It's not a sound that I'm hearing but rather it feels like one wheel is driving and the other is falling off a curb, like if you cut a turn too tight and the rear wheel hops off a curb.
Yeah the limited slip differential was my second guess.
Just to be clear I'm not complaining about a problem that needs fixing, but rather the car feels strange during that driveway transition.
Is what I'm describing normal for our differential?
maybe one wheel is driving and as the other wheel starts to hook up it catches and creates a bit of a slap effect..?
My last car was an Audi all-wheel drive so it felt totally different.

That is one of the most annoying thing I found with the Shelby.....people just get too close. I am just paranoid about them tapping my rear end.

No. HSA keeps the brakes on, it doesn't apply them.

BTW it happened to me again today as I was pulling out of a parkinglot through a curb onto the street and again it was jarring, as I was pulling the car out it felt like one wheel had the brakes on.
I forgot to turn HSA off, but I will test that in the next few days.

Have to admit, I haven't noticed this behavior. Pretty sure my HSA is on. Will check it out and see if I can replicate...

Update

ok so I finally turned HSA off and tested on that same curb entrance to the street and I didn't get the same rear wheel hop/interference so problem solved, this stupid setting stays off.
As a motorcycle roadracer I do not use all the new electronic aids anyway; TC, ABS, I turn them off, I'm more old school with the rider control. The Shelby is a different animal and needs some of this for performance, but this HSA in not one of them.
