I registered just to respond to this.
That is not a minor accident.
I'm pretty sure there are horrifying pictures of accidents where children were injured expressly BECAUSE they were forward facing. There are many aerospace engineers (not car buffs, car salesmen, or mechanics) who advocate aft facing airline seats because test data overwhelmingly indicate that the body can sustain MUCH greater impact forces when being pushed into the seat versus out of it. Thats why many army air transports orient the seat backwards. The ONLY reason we don't ride that way in commercial vehicles is consumer preference and convenience... NOT safety.
If the alternative is back row seating in a minivan or SUV, something nobody seems to question, I wonder how my kids would be affected by that same crash in our Honda Oddysey vs. our Volvo. True, the Volvo puts their feet closer to an oncoming vehicle, but the minivan puts their heads, necks, spines and organs considerably closer. Get a tape measure and compare the two. The rear seating in our van "feels" more normal but is 1) closer to the impact zone and 2) seems much more likely to injure the occupants in a frontal offset or nearly any other kind of accident since the kids would be projected forward (and their necks whipped forward at say 50MPH) vs. being pushed back into the seat.
Keep in mind that fragile babies and infants are mandated to ride rear facing for these same reasons. Just because the seat is in the "way-back" doesn't by definition make it any closer to harm than the 18" or so distance in the typical minivan or SUV.
Physics people. It looks scary because were not used to it but it seems to me no more dangerous than pretty much every single minivan or 3 row SUV you pass. Willing to be shown where I'm wrong, just sick of seeing the fear mongering whenever I come across these threads.
BTW, I am sorry to hear of that accident. Don't get me wrong, the pics are TERRIFYING!
