Out here in europe, they usually come with the "second cheapest" (and more expensive) options when buying a car (so the base model doesn't have them, but one "level" higher, you get the automatic parking brakes, automatic AC, cruise control, etc.).

They're usually a pain, because if you want to tow a vehicle with them, you either have to turn the vehicle on, to disable them (not always an option if it's an electrical issue) you have to find the manual release (if the car has one), or in some cases, even remove both rear tires and unscrew a part of a brake assembly.... but yeah... not that odd, with an old renault, you had to remove a tire to change the front light.
