What makes this dumb is all the driver had to do was pull the handbrake.... Also the can looks unopened? But either way that driver had multiple options on a flat road so super driver fail.
When in a panic the driver could easily just keep stomping the brake. In the accelerator mistaken for brake accidents some people have stress fractures in their leg because their pushing the accelerator so hard trying to stop.
If your brakes fail you should pull the handbrake if you even remember where it is, turn off the engine, and if worse comes to worst slam the transmission into park (guaranteed to break something though). Turning off the engine while in drive should really slow you down.
I haven't tried it but I think it'll work...
