That doesn't make sense. What do you mean, what will happen? Happen to what..?
This may have been the result of steering the car around a curve in the road while maintaining constant speed.
The term "steady speed" indicates a constant velocity. This implies that there is no net acceleration, and thus no net force. Any net force on a moving object will cause a change in velocity, as per Newton's First and Second Laws.
There is no acceleration if the car is travelling at a steady 54,000 miles per hour.
You have already stated its speed in the question !
Both the speed and velocity have increased as a result of acceleration.
If something is traveling at a "steady" speed, it can't be accelerating.

The forces on a car traveling at a steady speed are balanced. The driving force from the engine is balanced by the resistive forces such as friction and air resistance. This balance allows the car to maintain a constant speed.
The acceleration of a car traveling at a steady speed of 60 mph is zero. Acceleration refers to a change in velocity over time, so a steady speed means there is no change in velocity and therefore no acceleration.
Since the car is traveling at a constant speed, the net force on the car is zero. The forces acting on the car (like friction, air resistance, and engine force) are balanced to maintain the steady speed without acceleration.
Nothing
Since there is zero acceleration, the net force is also zero.
The term accelerating means increasing in speed, so if a car holds its speed steady at 65 mph, it is not accelerating. It is still running its engine, to overcome air resistance and other forms of friction, but that is not the same thing as acceleration.
cruising speed
A car traveling at a higher speed will have more kinetic energy than a car moving at a slower speed. So, the car with the most kinetic energy would be the one traveling at the highest speed.
