Now that I am old and don't drive cars that are borderline mechanically, I think the random stop and test program is a very good idea.
It's pretty much the same here without the "check points". If you're "rolling dirty" without proper registration they can impound on the spot but usually give you a citation.
In my youth I would have never passed a check point

My idea of a brake job was to go to the scrap yard and find a car with better brake shoes than I had. I think I was 20 years old before I ever purchased a NEW part.
Our roads and traffic conditions dictate that you have a better car than you could get away with back in the day. When you inter an Expressway( you can't get anywhere without being on one) you need toi be able to maintain 70-75 mph and be able to stop quickly or you will get run over. Conversely, stuck in 5mph traffic at rush hour on a warm day will test the metal of your steed quickly!
