Safety
 My wife was recently in an accident she was hit from behind very badly, she wound up with only a couple bruises from hitting her head on the ceiling of the van, but my 2 year old son who was in his car seat on the passenger side in the second row had nothing happen to him, not a scratch, the whole back was demolished to the point the car is going to be destroyed, but from where my son was sitting to the front of the car everything was o.k, Toyota said they have a thing called a crumple zone apparently it works, the rear crumpled so the rest of the car stays in tact. Needless to say we are buying another one with the insurance money.
