I'm sure some of it is done for TV effect but on the show I've seen cars with no doors, no hood, seats that weren't bolted down, total safety hazards that you would never get away with in PA. Here smog tests started in the cities and has spread out but there are still rural areas where no smog tests are done. I'm in a smog area but my SVT Cobra is exempt as long as I keep it under 5000 miles per year. I just bought a set of hi flow cats because I'm not sure I can drive it that little.
For those that haven't seen it, Pimp my Ride was a show on MTV for about 5 years where people would have a real beat car and West Coast Customs or a place called GAS Customs would turn it into a sort of show car. Wild paint, new interiors, nice rims and tires, and a lot of gimmicky accessories. They generally didn't show that they worked on the drivetrain so you had a show car with one foot in the grave. It's on heavy rotation at night on Speed Channel right now.
I'm sure thorough inspections for road worthiness that are performed back east have a lot to do with the fact that you have rust back there. As in, rust that destroys cars in short order if they are used as daily drivers. In California we have so many cars, in fact so many new cars, that attrition via the used car market all but ensures that practically every car on the road is road worthy. Before I bought my G37, for 8 years I drove a car that by all outward appearances was a hooptie. An '89 with clearcoat failure. Now there are many migrant field workers in California. Many here legally, many here illegally. For the past decade I have witnessed over and over that every field worker was driving a nicer car than I was. Without exception. Ever since some idiot law passed that bans busing of workers in and out of the fields, this has become even more noticeable. (I'm not a fan of this law because lots of cars coming off the fields means lots of stone laden mud on the road and in the air...hood chips ahoy.) These cars will go 150, 200,000 miles more with little problem. Shoot, my hooptie has at least 100,000 miles left in her. Now, I'm not going to say that every car on the road is a model of safety. But I think something along the lines of my reasoning described here, plays a part in the law-makers' thought process. Inspection programs aren't popular in California. Smog inspection is a necessary annoyance. People wouldn't go for safety inspections. The law-makers wouldn't go for safety inspections. They wouldn't want to be bothered! They already have to take their cars in for smog!
Since you mentioned catalytic convertors I will diverge from topic a little bit, do a little segue...
About California smog inspections I will say this. Nine years ago I did a favor for a friend and drove his car up to him in Portland, Oregon. Ah, Oregon! Who in Oregon isn't a nature lover? Anyhoo, one thing about Oregon stuck out like a sore thumb. No cats. The roads stank. Nasty, asphyxiating car exhaust odor behind any car, new or old, the likes of which I hadn't smelled since 1970's childhood family road trips to Disneyland in Anaheim! 1970's LA smog = 2000's Oregon highway air! What was worse was I had been so used to decent air that it was really sickening. In the 70's constant exhaust fumes, in all their tetra-ethyl lead laced glory, were the norm. Over time, the requirement for catalytic converters means pretty much all cars on California roads, excepting the rare classic, do not stink.
Back to the original topic regarding inspections and rust buckets and all. I still happen to have my very first car. A 1974 914 bought in 1986. I really need to get rid of it because the space will be worth a lot more to me than the car for the next half-dozen years at least. I mean, I will have no business spending even a minute of time towards any kind of restoration on that car, as cool as that would be, for the next 10 years, if not a few more. Anyways it sits outside. Uncovered (the cover, now 25 years old, has sat in the front trunk for the past decade and a half. The last time I drove the car, it was dirty enough I just didn't bother to put the cover back on.) It's got rust. It has moss growing on it for crying out loud! But I tell you what. It hasn't rusted
through. I could clean out the moss. Wash the windows. Scrub them a bit. Put a fresh battery in that sad, neglected vehicle, and start it up. And it would be road worthy. Ship it back east and drive it through one winter and it will be dust. But leave it where it is, another 10 years, not much is going to change except it's just going to turn another shade of ugly.
Alright, I hope I haven't bored anybody with my long-winded, pseudo-allegorical spiel. All it takes is a good glass of wine, and even more than usual, I have many words to say, that say very little. :bolt:
