What if everything was bouncy?

Bouncing boobs are enough for me.

There must be some situation where it would be really bad for something to be "bouncy"... but right now, I'm struggling to think of one...

I was going to say that it would cause chaos for cars and public transport... but on the other hand, it could be beneficial in terms of passenger safety and damage expenses, I suppose...

... but how would something like a car even work, I'm sure there are some components in a car that are definitely not meant to be bouncy... Nuts and bolts and screws? They probably shouldn't be bouncy...

I wonder (and this is question best answered by physicists) whether a world where everything was bouncy would result in everything bouncing off everything else and causing absolute chaos, making human civilization as we know it impossible. One thing would bounce and cause a chain reaction that spreads across the planet and becomes exponentially bouncier until everything flies off into space.
