Ghost C, you are quite possibly the most ignorant person here at GTP.
Why, because I disagree with you? Amusing that you've resorted to name calling this early in the debate.
What you think and what is fact appear to be quite different. Your reaction time is 0.013s? Reaction to what? You cannot stop a car travelling 160 mph in 0.013s. You can't even think about stopping, and then hit the brakes that quickly. All of us here appearing to be "grandmas" are speaking from experience, and from the sounds of things, you probably should be listening. Your age isn't listed, but I can only guess.
The definition of a reaction time is the amount of time it takes you to react to a situation that occurs. Like having to hit your brakes. So yes, I can in fact think about stopping and hit the brakes in that amount of time.
Take not that I never said I could
stop a car travelling at 160mph in 0.013s - I merely stated that is how long it takes for me to react to something, because someone said it takes between 1-2 seconds for a person to react. This is totally untrue unless the person isn't alert, and let me tell you, when you're going 160mph, you're fairly well alert.
Edit: A quick estimate says that to overcome the air resistance at that speed, you need in excess of 300 hp. That's a bit more than a Geo Metro has.
A quick estimate
for what, may I ask? Once again, not all cars are created equal. I'll tell you now that your quick estimate is off.

He drives a 1991 Cadillac DeVille. I'm guessing 69 years old.
Does it matter how old I am in the first place? What, I must be young because I'm arguing a point with you? OH NOES, HE DISAGREES, HE MUST BE 12.
Carl.
Most sports cars need well over 300' to stop from 100mph, and unless you have some sort of decelerating rocket on your Cadillac, it will more likely be around, or over 400', so I'd like you to explain how exactly you could stop short of the distance you can see with your low beams.
If my high beams can illuminate the road for more than a quarter of a mile, that's 1,320', do you think my low beams are totally one hundred percent trash? I said the
minimum distance that you must be able to see a person is 300' - I didn't say my low beams can see 300' and that's it, stop reading what you want to see.
But, for the record, I've got significantly stickier-than-stock tires, mounted on lightweight wheels. My front brakes are 12.8" rotors, with metallic racing brake pads, and 11" drums with high performance shoes in the rear. Stock, my car takes a little under 200' to stop from 70. That means stock everything, including curb weight. My car is three hundred sixty nine and three quarters of a pound lighter than stock - One and a quarter pounds heavier than a Ferrari Enzo.
I don't know, I think my brakes might not be adequate for my vehicle.

ALL of them were overdriving their headlights. From the March Car and Driver, they list the stopping distance of both a Porsche 911 and an Aston Martin Vantage at about 160 feet. That's from 70mph. Stopping distance increases as the square of the speed. So stopping from twice as fast (140 mph) will take 4 times the distance-- or 640 feet.
So that's it - There is no possible way to do anything upon seeing someone or something in the road except to begin braking and stay headed straight. Awesome, I thought most roads here in the US were 2 lanes, with highways being 3+ in one direction usually. I guess that's just an East Coast thing...
500 foot beams? That gives you 0.75 seconds to react, and stop the car. Stopping the car from that speed in that short of a time is equivalent to an average braking force of 80g. Formula One brakes are capable of 4g.
See above.
Do you want to stop pulling stuff out of your ass now?
Can you tell me what, exactly, I "pulled out of my ass" as you put it?
