Yup, exactly. And speaking of Ferrari's, I was at one trackday where rich guys brings out a Testarossa. It was nice to see but... he brought two Ferrari mechanics with him, just in case. Incredible. He ended up losing his alternator belt, and it took the two mechanics over two hours to change the damn thing.
Here's a vid of my car from Waterford MI with a Lotus Elise. Really fun track for a small car, but it's pretty unfriendly to mistakes. Ahh... you gotta love Youtube commenters...

And a highlight video I put together, but they muted the sound.
I wonder, if I'd had the engine noises turned up if it would fool the sensor?
