Kind of rich to talk of unsubstantiation when you completely lack that yourself. No substantiation why you believe this random speed allocation holds any merit, nor why you believe the hard data on overtakes is incorrect.
If reality doesn’t line up with your dream world, making unsubstantiated claims won’t magically make things real. The amount of overtakes and on who of people is simple, hard data available to anyone. If you don’t want to look at it because it doesn’t line up with your perception of reality, that’s your problem, but to then talk of “irrationality, unsubstantiation”, is mindbogglingly crazy.
