thx @catshirt, I note this about my Camry: "Toyota Australia announced that its accelerator pedals are made by a different supplier and that there is no need for a recall of Australian made vehicles".
Reading through the notes I see trying to turn the engine off while going effects various electrical sub-systems. Me, I'd try putting the car in neutral (auto).
A couple of years ago the alternator blew in my car. The battery had enough charge to let me drive +30km home after a re-start by a local RAC. When I drove the car the three kilometres to the shop, the charge started to drop and battery failure light (alternator failure) clicked on.
First the car started loosing systems: seat-belts, overdrive, ABS... etc. This continued, till I bunny hopped the car into the garage where everything stopped working. No doubt a sticky accelerator is scarier than the lurching I had in busy traffic, kept going till the end. Power steering was the last to go, then the engine itself.
"Koua insists that his 1996 Toyota Camry sped up to between 70 and 90 mph despite heavy braking."
