| 250 fleet vehicles crashed per year? WOW! At my old department, everytime a cruiser was wrecked/crashed, the officer wrote on the paperwork, "check brakes!"

Well, if you know someone that does auto accident reconstruction practice using the data from the event recorder, invite them to play with the wreck and keep the info to yourself. It will be interesting to see how fast the car was actually going prior to deceleration and impact with deployment of airbags. I did this once and had to keep this to myself - officer stated going only 5 mph prior to being t-boned and turned 360 degrees into a pole. Event recorder indicated 28 mph. If you are going to repair this go the whole route, at least you will know.

We get all sorts, officers backing out of stall hits other parked police car, responding code hitting each other, driving too fast and loosing control, opening doors into traffic and we do get hit by the good citizen's and tourist population.

| I realize this reply is not very timely, but let me throw this out there. A lot of claimed brake failures are not failures at all, but rather the ABS system acting exactly as it was intended. It typically plays out like this: Officer makes a somewhat aggressive and/or erratic turn/lane change, etc., upsetting the balance of the car and making one or two wheels very "heavy" and the remaining wheels very light. Picture a hard left turn where there most of the forces are on the outside tires. The ABS system determines how much brake it can apply to the tire with the LEAST amount of traction (the unweighted ones) and only applies that amount of brake at all four corners. Therefore, the officer steps on the pedal and almost nothing happens. Had he/she allowed the car to stabilize for a split second prior to brake application they would have had full braking efficiency. Hope this helps some...

Don't all officers get thorough "defensive driving" training? I've always said that you don't want the first time you push your car to the limit to be when it's unintentional. This goes for civilians as well. I generally take whatever cars I buy or will be driving a lot and do some panic stops, hard cornering, and the like in a big, empty parking lot. Preferably I would do it twice, once in the dry and once in the wet.
Even under those controlled circumstances I was pretty surprised to learn my current car has no ABS! It's been a while since I owned a car with no ABS.
