    A manually-shiftable automatic obeys your suggestion to shift if and when it feels like it. A manual transmission shifts RIGHT THE FUCK NOW as you move the lever.

      I have only tried paddle shifters on other people’s cars so I couldn’t do anything too exciting. They will really refuse to shift sometimes even if the result would be within the operating parameters of the engine/transmission? Is that just a problem with some models or is it universal?

      I do admit that I enjoy the feeling of being able to blow up my engine if I feel like it… (Actually I’m not sure the synchros would let me do that.)

        To be clear, “an automatic with paddle shifters” (or in general, a manually-shiftable automatic) does not necessarily imply a fancy dual-clutch transmission derived from F1 cars or whatever. Sometimes, like in my automatic-transmission car, it just means you get a + and - on the gear lever and still have a torque converter instead of one clutch (let alone two).

        But yes, the one thing that is true in any modern car without a third pedal is that when you push the stick to + or - or pull on the paddle shifters, all it’s doing is sending an electrical signal to a computer that mediates between you and the car and decides whether your input will be followed or not. It won’t allow a downshift that would cause an overrev (probably in any car, even the most track-oriented ones), in many cases (especially in less-sporty cars) it won’t hold a low gear and let you keep the engine at redline but will instead upshift even if you do nothing, and in many cases it won’t hold a high gear as you come to a stop and will instead start you off in first again instead of fifth like a real manual would do. And last, but not least, those computer decisions and solenoid activations and whatnot take at least some non-zero amount of time, which – even if it’s a fancy dual-clutch and the total time interval between gear N being engaged and gear N+1 being engaged is way shorter than any human could manage – it can feel laggy because you give the input and then it acts, as opposed to a real manual where your hand on the gear stick and your foot on the clutch pedal are doing the action to the car directly.
