So I was driving Lenny's car around after shooting Lenny. Fantastic car, BTW. I got into a few wrecks, as I pretty much always do. After a bit I noticed that my car wouldn't stay on the road. It kept pulling to the right, and I had to compensate by pulling my analog stick to the left as I accelerated. So I stopped, and swung the camera around the car to take a look. It turns out one of the wrecks badly bent my front-passenger wheel, so it was sitting at about a 20-degree angle from where it should have been. I don't know if that was a scripted thing, or if the engine was calculating the actual physics. If the latter... talk about awesome!
