Or always try to leave room ahead for an evasive maneuver and use your rear view mirror when slowing & stopped. Rear crash avoidance is an option!
(I've done it once to get away from a transport truck that had locked its brakes after coming into a construction slowdown behind me with too much speed.)
On the vehicle ID mystery... what about an older Chevy Blazer? Has the rim lip detail the HHR is missing.
