Hehe... All the classic cars rush past sounding like a pack of angry 
bees, and then an F1 car comes out, sounding like an angry mosquito.

There's something deeply amusing about an angry but tiny animal...

I don't know about that - I tried driving my car with no silencer, and 
it was *actually impossible* to exceed about 25 MPH. The car simply 
would not accelerate, even on the flat.

(OTOH, it was a fairly old car. But normally it would happily to 90 or so.)
