Yeah, probably that. ;-)
Actually, what was notable about the F1 cars wasn't so much the speed,
but the *acceleration*. You see the cars go past on a straight, and it
looks just like any other road full of traffic. But we sat at
Silverstone on a corner. The cars would come up to it, go round it quite
slowly, and then just *VANISH* off into the distance like they wer toy
cars made of paper... it was pretty insane.
Also, watching an F1 car going round the tiny, twisty indoor circuit at
the RoC, I noticed that it sounded like the engine was on a limiter the
whole time. It produced a constant note like a tuning fork. Then the
driver did a few dounuts, and it's amazing how quickly the engine revs
up and down. Like it just has no flywheel at all! Heh.

Fo' shizzle! ;-)

Agreed. There was motorbike back in the late 70's, early 80's called the
Honda 400/4. I think it was the first to use a 4 into 1 exhaust sytem at
that engine capacity. Hugely popular simply because it sounded fantastic.
(It moved a bit too!) :)

Acceleration is determined by the power to weight ratio. A "normal" family
road car has perhaps 70-90 HP per ton, a fast sporty road car perhaps
130-150. A formula 1 car has about 1300 HP per ton.

Probably, without an electronic limiter the engine would likely self
destruct quite quickly. And for demo purposes I guess they turn down the
limiter to quite a low RPM to avoid needlessly damaging an engine. And the
driver probably just had his foot to the floor bouncing off the limiter the
whole time.

Pretty much no flywheel, no, that's why whenever some non-F1-driver tries to
drive one they usually stall it immediately. Once the car is moving of
course there is not really any need for a flywheel.

Hmm. Good point, though. Just about any racing engine is painfully loud.
And that logic may only apply to certain kinds of noise, and maybe only
to street vehicles. Something about how the resonator in the exhaust
pulls more of the exhaust out of the cylinders, allowing for a better
mix of fresh fuel and air.
Of course, it could all be made up by some anit-noise group...

Just don't put a straight pipe on it and drive around neighborhoods at
2:30am.. Or rev the engine incessantly next to someone in a car with the
window down. Its just not nice...

And try not to set off too many alarms on parked cars!

LOL, I totally agree. My mates have Harley's and I've often wondered what
locals think about the noise.

I had a friend who did rally racing. He had a car that looked like a VW
beetle that had been rolled down a hill. (It was.) It had a V8 in it, with
racing tires, two sets of brakes, all that. Was fun to blow away the camaros.

Only problems are: a) slow (faster isn't much faster, and costs double),
and b) limited number of "write cycles". And, no, the 250GB one is not
