Variables such as tyre pressure(which also varies with temperature)
and tyre wear will make the crystal error insignificant.

No matter how careful you are with your design, I think you will not get
even
close to a crystal's accuracy.
When you corner, your tyres walk sideways, each individual tread block
shifts
to the side as it touches the ground and takes the car weight and
centrifugal
force, the next block undistorted touches the ground and starts to bend
to
the side.
The same happens when you apply normal driving power to the wheels,
to a lesser extent, but it will be a limiting factor in accuracy.

To calibrate the distance/pulse figure of your system,
set your pic to count the pulses and drive a
fixed distance. Do you have accurate motorway distance markers ?

Is it true that they have, on the new version of windows
managed to increase the MTBF from 95 to 98 minutes ?
(That's why they called it 95)
