the speed of a car can be measured in s^-1 m right...
it could be said that a speed of a car the velocity was 15 s^-1 m which is perfectly acceptable...
by definition 15 s^-1 m can also be written as 15 Hz m just by definition...
what on earth does that mean??? is velocity not really a vector but a wave???

You are going to damage yourself by thinking.
Speed has units of
m s^-1 (or m/s or s^-1 m). You could call that 15 Hz m, since 1 Hz = 1 s^-1, but no one uses those units.
No, velocity is not a wave. Hz measures how many waves go by per second; m/s measures how far an object or a wave moves in a second
The units "s^-1 m" and "Hz m" are not typically used to measure the speed or velocity of a car.
The usual unit for speed is meters per second (m/s), and for velocity, it is also meters per second but with a direction specified.
However, let me explain the units s^-1 m and Hz m to clarify their meaning:
1. s^-1 m: The unit s^-1 represents "per second." So, s^-1 m means "per second meter." This unit is not commonly used to measure speed because it does not provide a clear interpretation. It may be interpreted as "the rate of change of length per second," which is not intuitive for measuring the speed of a car.
2. Hz m: The unit Hz represents "hertz," which measures frequency. It represents the number of occurrences of a repeating event per second. In this case, "Hz m" would mean "hertz meter." The combination of frequency (Hz) with a length unit (m) is again not a conventional unit for measuring speed or velocity.
Therefore, it is not accurate to interpret velocity as a wave based on these units. Velocity is a vector quantity that represents both the speed and direction of an object's motion. Speed and velocity should be measured using the appropriate units, such as meters per second or other standard units for motion.
