Just crashed into a Lamborghini!

Except you don't. How many newspaper articles have you read where a person was pushed off their bike because it was a BMC and not a Brompton?

And as I said.. they are more efficient ergo save time and energy.

The price difference is also VASTLY smaller between a cheap and expensive bike... and still cost less than a ferrari mirror.

But non-supercars also get vandelised on a daily basis, so I don't see the point of the first point.

Fair enough on the second point, it's a pretty small difference though, for example on my beach cruiser it takes 5 minutes more to travel 8 miles than my fixed, despite the fact that it's exactly twice the weight and has tyres that are 3 times wider.
