All the cars added a marginal [ O(10ft) ] amount of braking distance at wide open throttle; with the exception of a very powerful, heavily tuned sports car which was the only one able to overwhelm its brakes.
If we convert MPH to FPS we can look at the data as follows:
70 MPH: 102.667 fps
100 MPH: 146.667 fps
CAMRY, V6, 70-0: delta 16 feet, .15sec
CAMRY, V6, 100-0: delta 88 feet, .60sec
INFINITY 70-0: delta 9 feet, .08sec
INFINITY 100-0: delta 6 feet, .04sec
We're talking tenths or hundredths of a second of unintended acceleration. A cursory search tells me reaction time to visual stimuli is about ~250ms.[1][2]
This means that in all but the Camry 100-0 case your reaction time is a larger factor in braking distance than the presence of wide open throttle.
