That's a very good idea, but I don't like the reset.

If a MCU is used for this we could add an extra non driven wheel pulse for
every fourth to tenth non driven wheel pulse to set the amount of allowable
wheel spin. Negative pulses that occur when the counter is at zero is
ignored.

On stick shift cars a minimum rpm for operation can probably make the clutch
switch redundant.
