I once messed with using linear programming to approximate this, and I have to say you did an excellent job explaining it!

Worth noting that the tires and gliders are independent, so one can first find their pareto frontiers, then combine that with those of the drivers for all dimensions

The switch from 2D to 3D was so seemless and beautiful I actually gasped.

Thanks a lot! That was my goal. It's a trick I learned: if you zoom in from a distance, everything appears flat. The effect is achieved by zooming out while simultaneously moving the camera closer to the subject!

In cinematography that is called a dolly zoom [1] and it is best known for being used in Vertigo [2] and Jaws [3].

My 9 yo is better than me at Mario Kart but not by much. This knowledge may make the difference for me. Thank you!

In summary: the difference between raw talent and experience.

Your kid has likely better reflexes and motor skills than you have, but on your side you have experience and wisdom accumulated over the years :)

You have a lot of options to choose from. How to pick the truly best option? Let me show you a method, in which you arbitrarily pick 3 out of 6 attributes and then use an artificial, unintuitive interface to choose an optimum trade-off between them. And once you do, my super-amazing method will tell you what combination to use, easy!

OK I might be an old bitter cynic, but the beginning got my hopes up for something clever. The only value I see here is explaining the Pareto frontier, but it doesn't take a genius to independently figure out, if you have 2 attributes, and someone else has one of the attributes at least equal, and another higher, that someone else is a better pick…

Of course, what the article doesn't even touch, is that some attributes could get worse results as they get higher: imagine having an acceleration and speed so high that you effectively can't steer your car.

Also a pedantic argument could be made on the cosmetics possibly actually affecting performance…

I thought it was a clever relatable way to explain the concept of the Pareto frontier. And that of the 703560 builds, you can pick just 14 and choose among those depending on what you prefer was a surprise to me.

I love how that transition is relative to the scroll position rather than working off a breakpoint. Did you consider doing the same thing with the first bar chart? I think it would be nice to slowly reveal the standings :)
