The car undergoes "hiking" all the time due to Universal Acceleration.
And what is "hiking" meant to be?
That's why a constant gas will accelerate the car for a while till it reach constant velocity.
No, your UA BS has nothing to do with it.
It will accelerate the car for a while because it is applying a force.
Eventually you reach a point where friction (including drag) provides a counter force which balances it. This means no more acceleration (at least relative to Earth).
The air medium is another case. The acceleration moment will be longer. To reach big velocity is a piece of cake as long as the airplane design can bear such big velocity (etc).
Nope, pure BS.
If this was the case car designers would not be spending any effort on making cars aerodynamic.
The simple fact is aerodynamic drag is a major limiting factor for speed for both cars and planes.
It is only easy to achieve high velocity if you have enough thrust to overcome the drag and you have the structural integrity to withstand those forces.
I guess there's been a drama, either in navigation or 'design' ~
Nope, you are the drama here.
