Formula 1: Building the world’s fastest cars

I don't understand why on Hackernews we change the titles of the submissions, if the originating site (a repudable arstechnica in this case) has the original title of "Formula 1: A technical deep dive into building the world’s fastest cars".

And with gems like this in the article, how someone couldn't say that it's technical?

"For example, each Formula 1 team is only allowed to use 25 teraflops (trillions of floating point operations per second) of double precision (64-bit) computing power for simulating car aerodynamics. 25 teraflops isn't a lot of processing power, in the grand scheme of supercomputers: it's about comparable to 25 of the original Nvidia Titan graphics cards (the new Pascal-based cards are no good at double-precision maths)."

Yes coming from a From an rnd background I was surprised that they are limited to half scale tunnels.

IT would make more sense to limit the max power for you computing resource - it would encourage innovation.

The tunnels themselves can be full size (which is good for reduction of boundary layer effects) but the models are typically 60%. There do exist some 50% models for cost reasons, but the correlation is worse and there are problems like the pirelli-supplied model tyres (amongst many other things) tend to be a bit crap.
