Saw that the Model X has side view cameras instead of mirrors.
I've read that the side mirrors can add a lot of drag, I've seen figures of one point (.01 increase to the CD). This seems like it would make a relatively big difference at highway speeds, and going with cameras instead of side mirrors could possibly increase the range by an amount of around the magnitude of going with aerodynamic wheels.
The Model X's side cameras are awaiting approval due to regulations. Any chance the Model S would have cameras too? If not, it would be really cool if they made the Model S have all the software/wiring/etc needed to have cameras, but just put in mirrors. This way in the future, if the cameras are approved, we can get side view cameras as a future add-on upgrade, and it could become an option in the future for first time purchasers too.
But, other than the aerodynamic advantages, side cameras are just SO COOL. :)
