A “closed course” means that the only vehicles on it are the ones needed to shoot the commercial. The filmmakers will get a permit to close a certain portion of road or other area and keep everyone out. This prevents an unsuspecting person from wandering into the path of a speeding car.
Even simple shots can require hours of set-up. You need lights and reflectors, the camera people, the support people, support vehicles, props, the vehicle itself and its driver, etc. Then there are rehearsals of the maneuver and usually several “takes”.
If you look close besides the words closed course it will also say professional driver.
It is a CYA statement by the car company warning you not to do this on a public road. By using such statements if you do attempt what is done in the commercial they have a defense in court.
Another way of saying “Don’t try this at home kids.”
It’s a way of advertising 'Look! You too could have a car that does this! But don’t do it! No, that would be illegal, so no way would we want to suggest that you do it. Uh, uh, no sir." What’s shown in the advert and what you can legally do yourself are completely different things.
Similar to the way the same advert will quote a price and then have the little disclaimer to say that the price they’re talking about and the model of the car they are showing are two completely different things.
So, to second guess the OP, it’s a way for the advertiser to show a car doing what would normally be impossible without breaking the law at a price that isn’t relevant. Aren’t adverts great?
A lot of “closed course” commercials are shot on test tracks as well, rather even than closed off or secured public roads.
Interesting, I didn’t start this thread, but when I put the first reply (and a silly one at that, I shouldn’t have) there was no OP. But now I’m listed as the thread originator.
The real OP has been lost to the hamsters of oblivion.
The disclaimer I often see says “Closed course. Professionsal driver. Do not attempt.” I think what they’re really trying to do in this case is to keep boneheads from attempting a maneuver they saw on television and killing themselves.
Erm… Or what Rick said.
It takes the term Hijack to a new level
