Anent nothing in particular, a suggested tech for the S-cabriolet? http://www.gizmag.com/savage-rivale-convertible-system/21973/
On a supercar prototype, 3.4/205 ...
That is pretty cool, I must admit
Got one on our volvo c70....
Even cooler: Vanishing doors
@Volker.Berlin - I recall seeing that when the prototype was on sale on eBay Motors in 2008.
This video shows the door from the inside. It looks to be very thin - basically just the outer shell, window mechanicals and a curtain to keep you from getting tangled up in the works. That's quite a contrast with the extra-thick doors on the Model S, and the primary engineering challenge would be a five-star rating for side-impacts.
For this, however, I'd be willing to sacrifice door pockets. :)
