Yes, 10s is the approximate margin of collision persistent for current
implementation. Therefore a driver needs to report collision events
constantly to update the last_color_collision.sec to trigger CCA. I
could add some comments on this as an initial implementation and a todo
for note - maybe we can come out with a better method in the future.
