This rotational mass / moment of inertial is not something I dreamed
up. It's a performance issue of which Honda itself is keenly aware:

"... Honda engineers wanted to keep the S2000 powertrain's entire
rotational mass to a minimum, thereby minimizing inertia, and the
response time between driver input and vehicle reaction."

"As an added benefit, putting lighter wheels on the car can increase
your engine's apparent power. Why? Well the engine has to turn the
gearbox and driveshafts, and at the end of that, the wheels and tyres.
Heavier wheels and tyres require more torque to get turning, which saps
engine power. Lighter wheels and tyres allow more of the engine's
torque to go into getting you going than spinning the wheels. That's
why sports cars have carbon fibre driveshafts and ultra light alloy
wheels.

I'm very pleased with my purchase. It's a fine car that can
comfortably seat adults, offering a sportier ride than a Toyota Camry,
and I plan to enhance the vehicle's strong points and enjoy owning it
for a very long time.

And so you are ... Honda's good will ambassador to first time Honda
buyers?

I put a lot of time and effort into composing questions as thoughtfully
as possible, and then posting them in forums where they are most
relevant, and the worst part of process is not the well intentioned
mis-information that is all to common on the internet.

It's jerks like you, who show their ass while offering nothing of
value, not even a meaningful critique of the questions posed that helps
bring relevant issues more clearly into focus.
