Except if it actually happens to you or a family member.
A number of years ago my husband and I went for a test drive in a Dodge Caravan and the accelerator stuck. Luckily my husband was able to shift into neutral and pull into a parking lot. The car salesman from the dealership was with us and it scared us all. It was used but still, these things should not happen.
My brother's stuck accelerator story was in a Dodge Viper. Much scarrier with a stuck pedal and 500 hp.
No luck involved, anyone qualified to have a driver's license, should know how to shut down a vehicle that malfunctions like this.
I had this happen with a turbo Thunderbird, about 25 years ago (floored, 3rd gear, floor mat). I had the car in neutral, and turned off, within a second or two. I never went back to the car wash which had cleaned my mats, and reinstalled the driver side mat backwards.
