Black Used

Why are black boxes in vehicles used in court?

I heard they are very inaccurate. It is well known to say an air bag was deployed it was never was or will say a car to 25 mph when going 75 mph or 75 mph when it is 25 mph. usuley the first time after errors is that routine maintenance and oil changes, exchange transmission fluid, Accelerator implementation, or almost nothing. Why use this black box to the court when he is only just 50% of the time.

Insurance companies love. If you are in an accident during 1 mph above the speed limit, he refuses to pay your claim in May. I changed buy a new one truck manufacturers because they will not delete the table before the sale EDR (Even when there is no law requiring that the vehicle). Think I'll buy an old truck and spent thousands of renovation.
