Spring actuated start gate with reset switch for the lane timer.  The 1/2" dowels are set in a 2x4 that is mounted to the bottom of the track with a short piece of piano hinge. 

The trigger is mounted on a piece of all-thread.

The 4 ft. skid ramp at the end of the track is half an inch high and is covered with black electrical friction tape.  There is a 2" foam pad at the end but only the fastest cars get that far.  And even then, just barely. 
Car accessories aren't damaged by crashing into a pillow at high speed.
