When I was younger and less wise, I drove my Corvette at such a speed that the speedometer stopped registering and blinking "188". That was down a long straight hill, with no crosswind, and at 3:00 in the morning (and for any police reading this, it was about 25 years ago, and the statute is decades expired, I hope...). I have also taken a motorcycle over 150mph; again, that was in the early 1980s. Nowadays, I seldom drive over most speed limits, and only then to pass a slower car safely before returning to the legal speed. And on motorcycles, I still tend to want to open it up, and take canyons at a few multiples of the speed limit , but I do so in a mindful way.
