On a related note, I came across an article in the Blue Oval News, same subject, tonight. 350,000 police units, 20 years, 14 police deaths due to the rear-end collision fires. There was also an incident recently where a female officer was inside on of the CV units and was rear-ended at ~100mph. She survived because the cruiser had the new plastic shield surrounding the fuel tank... Free for the police, $150 for you to buy and install.
Also a collaboration with reps from the aerospace industry for installing fire supression systems as another safety measure.
