Renault Twingo Concept Car – How Many Ipod Docks Do You Really Need?

There’s like one for every passenger. Apparently, there’s also a mixer so you can be a DJ while you drive.
 
I just want to know what the hell is that light bulb-y looking thing next to the row of the ipod row. [Edit: I've since been told that it is a gear stick. Hmmm...then why does it look like a light bulb? Anyway, it's a concept car so it doesn't actually have to drive...]
