It's deliberate. It forces you either to go in "newbie presentation mode" where you can reset & repair your car or in "simulation mode" with no car reset and no magical car repair. There have been lengthy discussions about this and it's not going to change

FYI, here's a huge moan thread regarding this, if you're interested (maybe some people enjoy reading through all that drama whining, I dunno )
How many times per second can human register changes?
(Hint: It is not 100 fps...)
Same kind of things you can find on hifi: "Golden plugs gives you a better sound quality", "Rotate your power cord to other position in socket to optimize the sound quality (180 degree phase change...)" and so on.
30 FPS is what humans can see if im not wrong, but autist, like me and some i know can see up to 80, which makes the glow tube light actually blink, giving huge headaches
