Yeah, this is probably the better idea. If the brakes are still working but are being overwhelmed by a stuck throttle, neutral also works. If that doesn’t, you can turn the engine off as well, though modern cars use vacuum-assisted brakes, so they’re going to be a lot heavier to use once the engine isn’t running.

However, what I will say is that people genuinely underestimate how a panic-inducing situation will affect them. This is why every single time you fly they go over the safety information, and you should pay attention to it. The number of people that have gotten stuck in a wrecked plane because they’re looking for the seatbelt buckle on the side like a car, rather than the middle, is insane. Same for those that inflate their lifejacket inside the plane and them can’t swim down to an exit.
