A vehicle can be shaking and knocking when the speed gets over 50 mph if there is something wrong with the suspension. There might be a tie rod loose, a wheel that is out of balance, or the ball joints could be bad. This is a very dangerous situation that needs to be taken care of before an accident happens.
Wheels are not balanced or ball joints
its chasis could be loose or its just old chasis being he thing that holds the wheels to the car.
My steering wheel shakes what could this mean? _____ try getting your car re-aligned.
Try having the wheels balanced.
Could be tires out of balance. Or a bad tire.
From 120 mph to over 200 mph depending on the vehicle.
As I remember ^^ Because once you start the engine you give it power so it start working, and this power is really so HIGH that your car can start from 0 MPH to 100 MPH or something like this. So for sure it would shake.

Ford GT40
yes the fastest car in the world is the Bloodhound SSC With over 1000 mph
It would be a transmission issue, not up shifting. If the engine is in "limp mode" it will not accelerate over a set mph.
