Don't blame you in the least.
Twenty-five years ago, I had a Mazda Miata with some modest suspension improvements, but it was factory stock otherwise. Lived in a place with serious mountain roads, canyons and drop-offs, ditches and rivers, and all sorts of boulders and critters in the road at unexpected times. Wanted to better-know how to avoid such messes, if at all possible.
So I did a couple dozen instructor-led track days (on a moderately twisty course). Done in order to push my car sufficiently hard so I'd know how it would behave in quick (even severe) maneuvers. Even in that Miata, top speeds hit about 105mph. But the car wasn't designed to be doing hard cornering at 100mph speeds. In the ~40-70mph range (and slower), it could be stellar, hanging with many very fast and competent cars. At those speeds, though, the fat cement walls surrounding the track's "danger" zones began to loom large. Had visions of getting the "stink eye" from the insurance guy, assuming I'd even bother with that discussion. Can't imagine a 4ft shorter Miata and a pitiful look on my face would go far.
Still, the training saved my bacon on more than a few occasions. Worthwhile, on one's "stock" street vehicle and typical tires, if only to know what to expect and how to handle it. Doesn't guarantee anything, that's for sure, but it can help.
Been to Laguna Seca, Thunderhill and a few others I can't recall anymore. Good times.
Which reminds me. Somewhere I've got a bunch of old photos of races at Laguna Seca. Out of countless hundreds of pics, there were a few that didn't turn out half bad. I'll have to dig those up.
