I think he is just being controversial - standard fare for many entertainment writers. What he says is obvious, modern car’s drive better, more comfortably and safer than old cars. And for this he is a famous motoring writer?
Objectively, our daily transports will drive circles around any of our classic cars on public roads (well, I don’t own a Miura ). Duh.
Furthermore, I dare say I would not enjoy being a passenger in one of my old cars on an event/drive of any significant length (eg greater than 1 hour) unless it were Redman, Michele Mouton, or Hans Stuck at the wheel. That’s why I leave my spouse at home, on classic car tours that don’t have luxurious destination events.
For me, old car’s are a selfish, self-centered pursuit of the pleasure is in driving a slow car fast ... cars that rely almost entirely on the driver to adapt to and make up for the car’s inadequacies. I like cars that make me a better driver, not the other way around.
Well, there is also the emotional aspects of esthetics & history.
So, sign me up to drive that mower
