I am 63 years old. I started driving 'manual' with little two stroke motocycles. (the 1960's craze, little motorcycles 50cc 100cc). And have always owned a manual transmission car EXCEPT once. And that car was the worst mistake i ever made. i sold it the moment it was no longer upside down to get another manual transmission.
I drive mostly in city traffic. Who cares if I have to row a lot to get anywhwere. It is the ONLY way i like it.
It does not matter to me what anyone drives. Just what "I" drive.
