Yes, it does seem the manual is on the way out. And the general public (enthusiasts included) is the axe-wielding culprit. It's a shame as I think manuals are SO much damned fun!
I'm just of the mind that a car designed for fun should automatically offer a manual as well. Pun intended
And I can't fault Corvette for not only keeping up with, but bloodying the competition. The C8 really is a spectacular accomplishment. Especially at $60,000 !!!
The last car to ditch the manual might be the Miata.
