I can imagine that, if I had tried everything else and failed to stop/slow the car, then I might pick up the phone and scream for help.
But that would have been after;
1] Pumping the accelerator a few times, see if the jam releases.
2] If not, (or at the same time with my left foot), pumping the brake pedal.
3] If they fail, knock the gear shift into neutral.
4] Last gasp, turn the engine off.
Only then, when everything has failed, would I search for the phone to order a pizza.
Question!
In the UK most cars are manual shift so there is no problem kicking the gear shift into neutral. But for the small %age of cars we have that are automatic, we have always been told not to change gear from Drive whilst moving, as that could damage the gear box.
Is that right? Not that it would worry me if I was hurtling along the freeway trying to avoid other traffic whilst attempting to slow down, but is there a mechanism that protects the gearbox from accidental gear shifting out of Drive?
