I find it very interesting to point out this type of thing, here is my (hypothetical) example:
In real life, I fly around in helicopters, drive mercedes, and wear rolex watches--but hypothetically speaking *if* I didn't have a whole lot of money and tended to drive older cars all the time that still needed to be smog tested and one of my cars failed the emissions tests, it occurred to me that it would actually be a very expensive thing to set "right" and still be 100% legal on. I believe that you get three "tries" or tests before you are exempt, and if your tabs are expired, that is three tests (which cost money) plus various (also costing) attempts at repair PLUS trip permits you must buy each time you move the vehicle on the road--all assuming that *hypothetically* the vehicle had not been used for a couple years. Its the government screwing with the small-timer.
