Back when I used to be on the Miata mailing list we had a formula for how fast you could take a corner in a Miata. It was something like Y = 2x + 10, where Y is your cornering speed in the Miata and x is the posted speed for the corner.
I remember driving I80 through Utah with my wife and seeing a corner posted at 65mph. I remarked to my wife, “I could take that corner at 140mph in this car... if it went that fast.”
My Mom bought a Miata the first year it came out and still has it.
The S2000 supposedly has a top speed of 160, and sure enough some clown had his girlfriend take a video of the speedometer while he ran it up to 157. I’m not tempted in the slightest to try it.
