I've gotten into the habit of RainX'n my windshield on new cars. The MS has been a blast to drive so I got around to doing it this morning with about 500 miles on the clock. While wiping the RainX on I noticed a bend in the front glass. It was not the normal curve of the windshield but a deliberate bend from the vertical to more horizontal about four inches or so from the top of the glass. This subtle change in direction of the glass was surely designed to keep flow attached as the already raked windscreen transitioned into the roof line. For anyone that has done FEA or wind tunnel flow analysis you will understand just how neat it is that Tesla chose to add another dimension to the compound curve of the wind screen in an effort to keep flow attached. Those guys are some serious nerds and that is a good thing where I come from.
