Here is a little personal experience of mine. I was going about 20mph rolling up to a stop light and there was this jeep patriot on my *** so I decided to move over into the right lane (I was in the center lane) I gave it some gas and right as I move into the right lane he had at the very same time flew over to my side and I ended up slamming into his rear driver door while under acceleration with no brakes applied. Needless to say the impact was pretty hard and I pushed his jeep over the curb onto the sidewalk. I felt a pretty good jolt but I was perfectly fine. Wasn't even sore the next day. My truck had a big ol' dent in the bumper and the bumper was pushed in a little and rubbing the wheel, and my bumper cover was all scratched up and cracked. Total damage was about $350 parts and paint, I did all the labor myself. The Jeeps rear driver door was completely smashed in, glass shattered, all airbags deployed, and the passenger wheels were both bent upwards from being pushed over the curb. Driver was taken to the hospital from injuries from the airbags, and although he was shaken up a bit he ended up fine.
My friend (05 RAM 1500) and I were driving like idiots through a parking lot, it was raining and I was flying over speed bumps. I got pretty far ahead of him and came to a stop sign he tried to catch up and right as I came to a stop he slammed into the back of me at about 20mph while under 100% braking, his wheels locked up over the speed bump right before the stop sign so he couldn't stop. I saw him flying up behind me so I punched the gas but the turbo lag didn't let me move much so I still got hit pretty hard. Luckily I had my trailer hitch in so I didn't have any damage but his bumper got a whole punched in it. Again, I got shook pretty hard but woke up the next morning and wasn't even sore!
Finally, (yes I know I have been in a lot of fender-benders) I was out with some friends playing in the mud (at night) and my friend (06 F150) and I turned the same direction and slammed into one another front driver corner to front driver corner. My bumper got dented really bad, bumper cover was all cracked up, headlight was shattered (still worked), and fender was pushed in. His truck got f*****. Bumper was tore off, headlight ripped off, fender hanging down, hood crumpled up, grille cracked, pretty much the whole front drivers clip, drivers door wouldn't even open. But no airbags deployed and everyone was perfectly fine!
Bottom line is the SD trucks are very safe as are the new style F150s. I have never been in too serious of an accident but I know if I was I would surly be fine. If your getting any year SD truck I would not be worried about safety.
