I'm fortunate in not having to own a car.

What's kinda weird to me is the tendency to put ever larger engines in
4-place aircraft.

Mooney defined efficiency (and pretty much continues to do so) but
there seems to be a big market for 300+ horsepower engines.

I suppose if you're laying out $400K for an airplane and 4000 a year
on insurance, an additional 5-8 gph isn't a big deal.
