You will find yourself driving at the speed limit on the freeway, right lane because you don't have OD and just about every cars will zoom by you. Including those little Prius, Yaris or whatever. Muscle cars still rule the road, may be just on the weekends. Most people will take them out on a sunny day.
The muscle cars war is still alive, just fewer options. The 2015 Challenger will be out next week with the Hellcat to follow. Step aside little Prius, I got OD too (my YJ).
Ps, the Teslas S are very quick.
