Was involved in accident on interstate. The car in front of me began decelerating and as a result, I did the same. The car behind me crashed into me at high speed and pushed me into the car in front. (3 cars involved total). The front and rear ends of my car were completely crushed to the point where the drivers door will not open more than about a foot. At no point did my airbags deploy. My car is serviced regularly and no warning lights were on. I was not injured but am extremely lucky that this was the case. A police report was filed.
