"This can be tested on artificially generated data gaps, in places where one knows the actual surface temperature values but holds them back in the calculation. Cowtan and Way perform extensive validation tests, which demonstrate that their hybrid method provides significantly better results than a normal interpolation on the surface data as done by GISS."
When data points you in one direction, the number of conclusions you can draw from it is equally limited.
132 MPH isn't THAT ridiculously fast, but it is certainly fast enough that you shouldn't be doing it on standard production tires, even the ones rated for high speed, because they aren't rated for that high speed for any length of time
Any high speed tire (V or higher) with an "A" temperature rating should be safe for driving over 100mph (although for sustained track use you'd probably want a higher speed rating, and also need to pay attention to traction and treadwear ratings). Tesla has V rated OEM tires (rated up to 149mph), and this guy was doing 130mph for a short period of time, which was certainly safe as far as the tires are concerned. I wouldn't race along at that speed on those tires for a long period of time, though.
Personally I have no idea why people spend this kind of money on a car.
It's like the difference between cafeteria food and a nice restaurant. Sure, both get the job done, but spending more buys you a better experience (okay, not always, but let's not get nit-picky). Some people want a little more luxury, more features, etc, and if they can afford it, then why not? Leather heated seats sure are nice in the winter
