OK, some guy is clearly telling lies, I think... He said he did 190mph on the road, which is straight for 1 mile and then for half a mile has a hill.

This hill is pretty big, he says he was doing about 160mph when he reached the hill.

So, me being skeptical. I know if you hit a hill at that speed, you will experience gforce. So I asked him... Was the car easy to control and did you feel anything...

And he said "NO"

I said "Bullshit" and was kicked out of the class, but anyhow. I told my teacher it must be bull how could he not feel anything he must have felt gforce. Maybe about 3gs when he hit the hill at that speed!

I just be right don't you think guys?

Depends, what kind of car? What was the angle of the hill?

It can be done:

At that speed, drag is probably making more of a difference than g=constant anyway.

Accelerating to over 200 MPH would get you upwards to 3G's depending on just how fast you accelerated then if you braked very hard you could get upwards to 5 or 6 G's, there's actually more G's when decellerating than when accelerating in a car! You will also get lateral G's of up to 3 G's when you corner a car at high speeds in a sharp corner.

No, what muslim is talking about is the changes in g's (force) felt when the car encounters the incline, and later goes over the hill at 160 mph. And, yes, he is correct that the driver would feel an acceleration if the change in grade of the hill is large enough. The felt acceleration he is speaking about is due to a change in the direction of the car, not a change in speed. If the change in incline is very shallow, the driver may not notice the acceleration, but if it is fairly steep, a driver would definitely notice. It doesn't matter how good the car and its suspension, the driver would feel a downward pressure (increased g's) when first beginning the ascent, and both he and the car could experience momentary 'weightlessness' when the car topped the hill. It all depends on how quickly the grade changes and the speed of the car.

It depends on how gradual the change in incline is, if it is very gradual he may notice no acceleration, but if it is a quick change he will feel more acceleration.

He might experience 1.3-1.5, certainly not 3g. That would mean your body feels 3x as heavy.

What kind of car did have have ? I think it's bullshit..

Yes this is what I am trying to say. The incline is steep, I mean I drive on that road all the time, and I know one night I did some speeding... I was doing about 110mph I went up the incline, and my head felt heavy, and there was downward force, I almost lost control of the car, as I didn't expect that. Its also curved, the incline is steep and curved to the right.
