Was told by a bus driver that they usually travel at 70-80kmh on
the extreme left lane of the expressway even though speed limit for
their vehicle is 60kmh usually tp don't book them, unless they try
to act smart and travel on other lanes or they travel more than
80kmh.
Conclusion: No matter what vehicle you drive, try not to exceed
over 20kmh of the road / vehicle limit, you are probably quite
safe, unless the tp are really under quota or major operations,
then good luck to you.
