  • It’s not just about speed and acceleration. It’s also about control. Racing drivers face an infinite number of different conditions out on the track and it would be impossible to tune the transmission in such a way that it does exactly what the driver wants 100% of the time. And it really has to be perfect. 99.9% isn’t good enough because the other 0.1% can wreck the car if it does something unexpected while driving at the limit.


  • Modern, high end race cars are automatics.

    No, they’re sequential manuals*. Unless you’re talking about drag racing, where automatics are common.

    *Edit: Or they can also be sequential semi-automatics if you want to be extra pedantic. But personally I’d classify a transmission based on whether the driver has to select the desired gear, or if the computer selects the appropriate gear without driver input, because that’s the thing that matters in the end.






  • This is tax money funding toys for the parasitic criminal billionaires.

    What an idiotic and short-sighted take. Research on supersonic aerodynamics is useful for far more than just toys for billionaires. Military applications, rocketry and astrophysics, for example. And even regular commercial aviation, because supersonic shockwaves are a major source of drag even at the speeds airliners fly at. Airlines would kill to have a fleet of planes that burn a few percent less fuel.

    E: Also, much of the noise an airliner makes during takeoff comes from the sonic booms created by the engine fan blades going supersonic.



  • I would rather just have a singular name like “squajibbles” for milimeters and memorize an intuitive sense of what that is. I realize I can do that with the word “milimeters” too but my brain sometimes gets stuck on unpacking the math.

    This is, in fact, exactly what metric users do in their daily lives… We don’t do math in our heads every time we measure something. We know from experience how large all the units are and pick the one that’s appropriate for a given situation, just like you do.

    When you measure something using inches, you don’t then say “it’s this many 1/36ths of a yard” unless you specifically need to convert it into yards for some reason.

    Similarly, when we measure something using millimeters, we don’t say “it’s this many 1/1000ths of a meter”. It’s just a millimeter. Don’t get hung up on the prefix, just ignore it and treat it as a unit of a particular size.
