I never stated my rental kart experience made me an expert on anything but rental karts. That's why I rely on the opinions of all the professionals who are experts. But it's necessary to go over the edge to really understand where the edge is. That's why I spent time purposely over-driving. Of course there was no risk to my wallet or body, so why not? Look, I'm not trying to be a jerk. We just have some differences of opinion.
