What's that sound?

Oh, it's just the sound of a $400,000 super car smashing into another car, getting air and then slowly rolling to a stop on a London street. No big deal.

Someone just happened to be recording as this Lamborghini Aventador was cruising through London's Chelsea neighborhood on Monday.

A car pulled out in front of it, causing it to smash into that car, get some air and hit two other cars in the process.

It's safe to say it's going to cost a couple bucks to repair that thing.
