I've had the same experience on the 'Ring, I made it round a couple of times by (slow) car, which is relatively safe.
Once I tried it with my bike of that time, a 2006 Suzuki Bandit 650 (yeah...). Scariest track riding I have ever done, cars just see you as another kerb they need to hit... Never again :)
