So, I've had my Model S for exactly 1 week. Grin included, of course. But, just now as I was cruising down the highway midday, ( doing the speed limit ), I passed a GMC Acadia who was going a little slower. I got about 10 car lengths ahead and moved to the right lane, when they sped up to catch up to me. They didn't pass me though, they came along side to take a picture. Biggest GRIN ever ! Best car ever !
