I don't mean they lack the fun of going out and touring the landscape by itself, but the actual act of driving the machine.
Until I gave up owning a car a few years ago, I always drove secondhand cars that gave me a sense of pride of owning something that had original style (not wind tunnel designed same-shape-different-brand) and needed a bit of skill to drive them well (youngest car I owned was a 1996 Alfa Romeo 164 Q4).
Those now antique cars involve you in driving and not make you feel detached from them as if you sit behind a screen on the couch and just point to where you want to go.
