I actually wondered about this subject, as my 08 Charger and 2014 ram have the same angle and it doesn't actually look or feel right. I thought that if I ever got rear ended my neck would be folded down, chin towards neck and well, FOR ME that might be bad. I kinda left it alone, as I had my neck fused at C5/6 and some angles are now impossible, others are uncomfortable. In another words I thought it was just me so WTF , right?
I got rear-ended last Sept in my charger, I was stopped in traffic. Range rover hit me doing about 25 mph OUCH
I distinctly remember the car moving forward WITHOUT me. I was being pushed into the seat.
Guess what?
I didn't die or break my neck.
I was sore the next day, upper back and neck. seemed normal for what happened
I am pretty satisfied that the engineers know what they are doing, IRT this issue and although I think It does look a little dumb, Its built that way for a reason.
