why did my cars start to become fast?

Germany has it, but its not technically a factory option here's the Brabus amg e63 wagon http://www.autoblog.com/2013/12/08/mercedes-e63-amg-wagon-brabus/

So yeah 4-5x total cost would be closer. But you're going to need to up that comfort for that market.

I actually looked this up at one point: the legal requirement in the US for stopping distance is 70 meters (~230 ft). Taking a Consumer Reports page off Google, it looks like 45 m (150 ft) was toward the long end of braking distances in 2011, but presumably when the braking distance requirement was first imposed in 1968 there was some need for it.
