Just read about the new 2016 E Class technology and one thing really caught my attention. If the car senses you're about to hit from the side (don't ask me how it knows this -- cameras?) it readies the side impact airbags, but also (and this is really weird) pumps a sound through the speakers in the car that minimizes the sound of the airbags deploying and the collision itself. Crazy.

 

That is some pretty cool technology. I bet it will be awesome - just a nightmare when the sensors start to fail.
