I can double clutch; also speed shift, both upgear/downshift in my Miata, but I don't, as everything has to be exactly perfectly timed and flawlessly executed, whereas, perfection's not my usual modus operandi, in my "good enough" world lol :-) Too much chance and opportunity for damage to the drivetrain imho.
Timing is everything when you have to get RPMs matched exactly, you have to add enough RPMs when going to another gear to compensate for RPMs when you actually manage to complete the shift when the gears mesh.
Doable, but takes a lot of practice and experience, which seasoned OTR truckers make it look easy but it ain't nothing of the sort.
That's why for everybody else we've got automatic transmissions and synchronized manual transmissions.
Most people are not professional drivers and they're not ever going to reach up to that level of experience & proficiency acquired through hundreds of thousands of miles on the road, 11, 12 even 13-hour + days.
Not to worry, one of the "Ower-Operators" (as I refer to them) that I knew from back in the day tells me the "old Trucking firm" has purchased and is experimenting with it's first self-driving truck.
Seems in future robots will have to deal with all of the Hazardous/difficult/dangerous/boring work of humanity.
I'm hoping for The Jetsons and not Skynet terminators :-)
