From reading the next sentences, I doubt the officer did anything beyond adjust the direction to keep it more stationary by the oppositional force of their vehicle.

Given adequate highways, rotaries and traffic going faster, one can drive indefinitely without breaking, so while there's always a question of whether a notable incident is a stunt of some sort by someone who actually knew how to stop, etc, I don't see anything unlikely about the outcome.

In this case there is ample evidence that the driver tried very hard to stop the runaway vehicle.

I remember a few years ago there were run away semi-autonomous cars like this. But in almost every case, it turned out the user was holding the gas thinking it was the brake, a floor mat holding a pedal down, or there was a lack of data pointing to a car fault. So I would definitely take this with a grain of salt.

It was pretty trendy to report on these incidents at the time.

That said, if the article is to be believed, throwing the keys out the window and hitting the power button not working is a bit crazy. So is only having a "fly by wire" brake system.

And if an engineer did a black box dump and it reported tons of faults, it very well could be an error in the car.

Either way, I'm glad I own a car where my pedal is connected to the actual brakes, with or without power.
