jamuraa said:None of the airbags deployed - I was actually truly surprised at how bad the damage looked after the crash, given the low speed. The truck hit the car at what must have been the exact worst spot to cause so much crumpling.
The reason your car incurred so much damage is because when you hit the bumper of the truck, the frame of the truck (where the bumper attaches) absorbed some if not most of the impact. But the truck's bumper hit above the frame rails of your Leaf, so the hood, radiator core support, radiator, charging port, etc. took the full brunt of the impact.
It's also a common scenario between two passenger cars in a "panic stop" type accident. The car in front is hard on its brakes so the front end is down and the rear end up, and the car right behind it is doing the same. In some cases it's been known to cause the car in back to "submarine" under the car in front of it.
