My 2500HD GMC does the exact same thing. Started a few months ago.

I had this happen in my F-150 and actually hit a gas station because of it... After some detective work I found out that the boots I was wearing were wide enough to hit the gas while I attempted to brake... Essentially causing me to do s brake stand and lunge forward

& no I do not believe any Vette (or any car) can accelerate if the foot break is fully applied correctly (foot on the break peddle only)
But they all go like h when the idiot behind the wheel is pressing the gas pedal thinking its the brake pedal. The Audi fiasco is how come we have those stupid brake interlocks on automatic transmission cars so you have to have your foot on the brake to shift out of park.

When the engine is spinning slower than idle (say <15 mph in 4th gear) and I am still lightly on the brakes, it seems like it wants to accelerate. I realize my mistake and get it into a lower gear. Happens very rarely

Those interlocks are a good idea from an interface standpoint. No matter what you're doing, the brakes really should be pressurized before disengaging the parking pall and applying drive force to the wheels - in reverse, no less. At the same time, the system guarantees that the driver correctly identified the brake pedal.

Don't be so fast to dismiss the drivers as "idiots." All of us operate cars by habit and sense memory. Automatics will roll forward (or backward) at idle without the driver pressing the gas, which may necessitate a quick application of the brakes. If in that situation the car accelerates because the driver misidentified the brake pedal, his immediate reaction will still be to apply what he thinks are the brakes. If he panics, all hope goes out the window.

The downside is when the systems quit working leaving you stranded. Sometimes they have a button to override the system using the key, which is a PITA.

Sounds like the computer is trying to maintain the minimum idle. Shouldn't be in 4th at 15 MPH. Later! Frank

If your car is accelerating (really speeding up, not engine revving - there is a difference) while you are stepping on the brakes, then you are either pressing the gas pedal thinking it is the brakes - or - you are pressing both.

The gas pedal goes to teh floor, the brake pedal does not.

In a 'tug of war' between the brakes and the gas pedal, the brakes always win, as brakes are approx. three times more powereful than the engine on trhe average car. Think about it, you can decelerate three time faster than you can accelerate, and in one-third of the distance.

Physics is your friend.

I would also guess a messed up, wadded up floormat would be the number one possibility.

That brings back a bad memory from way back with my 67 Olds 442 auto. I almost killed myself when it decided to acelerate on its own even over powering the applied break. I had to shift to neutral and turn off the engine to get it to stop. It ended up being a left side engine mount that broke torquing the engine up on the left side thus opening progressively the carbeurator linkage. I fixed it myself but months later there was a safety recall from Olds about this problem. A scary event.

Yup. Happened in a ford escort. The floor mat was on the accelerator and the brake at the same time

My wife hit a wall because she says the car accelerated when she hit the brake. She said the message on the DIC was "ABS Active"

Default The floor mats are anchored to the floor on the Vette!

Note that the floor mats are anchored to the floor by snaps on both the drivers and passanger sides. This is to keep the rug from sliding into harms way with aggressive driving.

Not in the vettes, had an 82 Z28 camaro throttle stick, pulled the e brake and put it into a ditch. I was not smart enough back then to turn the key off.
