And where are you from? And how old? Not “do you” but just if you know how.
I’m in the US, mid 30s and can (and do) drive a manual transmission.
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.
