Heck! Even an old 10 speed Spicer would have them drooling with frustration!
My dad worked in construction for decades and he told me that back in the 50's Mack dump trucks had a weird transmission with 4 speeds on one lever and 3 ranges on the other.
Drivers of a certain ethnic persuasion could run through the gears like "Johnny playin' a bell" while the others stalled or burned out the clutches in no time. Apparently that talent has not rung down through the generations.
Try explaining double clutching to even the brightest i-whatever user. You'll draw a blank.
