Yeah, but he specifically stated that he's not really interested in lap times and performance. Driver involvement and enjoyment is the main objective, so if a manual gearbox is lighter and more engaging, and 99% of customers want one, then it's the obvious choice.
Everything is a compromise, and if you told me I could have a superb looking sports car that weighs less than a tonne, with a naturally aspirated V12 that revs to 12K RPM, and unassisted steering, I don't think the minor inconvenience of dealing with a manual clutch/gearbox on a long drive would put me off in the slightest. Nor would knowing that a DCT box would knock 0.5 seconds off my 0-60, because honestly, who cares?
And anyway...surely long distances are when a manual gearbox isn't really a chore anyway? I don't tend to change gears much when cruising along the motorway for hundreds of miles
