Playtest fixes: lit streets, steadier frames, better crashes

We played a full night and fixed what got in the way. Street lamps now glow all the way down the road instead of switching on as you arrive. Distant cars keep their real shape. Crashes no longer twist knees and ankles or sink the rider into the pavement, and they no longer drop the frame rate. A controller can now answer calls, and a START SHIFT prompt shows how to begin. Calls move faster, and the end-of-shift sounds are new licensed effects.
