No such thing as a safe spot to PIT someone, ever, let alone while they're asleep at the wheel. This is a great example of why people hate all cops, anyone with two brain cells to rub together would get in front of the car and gradually slow to a stop.
I agree with the recommendation that you yourself replied to: move in front of the vehicle, and gradually slow to a stop, with lights and sirens optional but recommended
I am thrown by the question of "What else should have been done" though, after grandparent made an explicit recommendation
