post the dent your wife put in you after she found out 
While what you say is certainly true, it feels like--and apologies if I'm misinterpreting!--like it's being negative about modern car design. Remember that much of that crushability is deliberate, to attenuate crash forces. While a modern car might be totalled by a shunt that an older vehicle would have survived, the inverse/converse/perverse is also true: a modern car driver will survive many accidents that would not be survivable in an older vehicle. I'm sure we've all seen modern crash aftermath photos where someone walked away from what barely looks like a car any more.Well you need to remember that 90% of today’s cars are just a bunch of cheap plastic and soft metal. If you’ve ever seen a rear end crash up close- the front of the car just comes flying off. Like a kid crashing a lego vehicle. And that’s why you see so many crashed car bumpers just left laying on side of road . Don’t ever assume that you have a real bumper that could take a minor collision.
Those plastic bumpers are not bumpers, but bumper covers. The real bumper is under the bumper cover. It is designed to absorb impacts. It is quite substantial. The bumper cover is just to make it look good and does fall away in the event of a collision. You should be able to see the bumper in the Sienna by opening the hood and looking down in front of the radiator.Well you need to remember that 90% of today’s cars are just a bunch of cheap plastic and soft metal.

The rear bumper of the Sienna is a joke tho. Im quite certain if i backed up into a flat wall - the liftgate and the "bumper cover" will hit it at the same time. Its almost completely flat back there. No room for error.Those plastic bumpers are not bumpers, but bumper covers. The real bumper is under the bumper cover. It is designed to absorb impacts.
