[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]I've driven wranglers for almost 30 years and comfortably passed one down to my daughter (and will be getting one for her little sister soon). They are plenty safe if you drive them properly. If they scare you, don't drive one and don't give them to your teen. They are not terribly practical or comfortable but they can go places and do things that your Volvo can't. Plus, there is nothing better than taking the doors and top off and enjoying a warm, sunny day driving on the beach. [/quote]

OP here. It’s not that I’m worried about her driving it safely. I’m worried about somebody else driving in safely and hitting her.  And flipping the wrangler.   Or the airbag not deploying.  Or the passenger hitting the roof.  All the things the IIHS notes.  [/quote]

Any and every accident is different.  Sometimes rolling is the safest option.  A kid from my daughter's school was hit in the side with a VW. The sun basically drove over top of him and he had to be cut out of it. Major life changing issues for him. He most likely would have been better off rolling over a couple of times.[/quote]

You’re not being very nice to that poster who probably understands a great deal more about physics than you do.

Without going into the minutiae of the dynamics of energy transfer during a crash, the one thing that’s important for you to understand is something called “Delta V”, shorthand for “change in velocity”. The higher the Delta V the greater the energy transfer into the vehicle and therefore your body. A smaller Delta V results in less energy transfer into you.

So an impact that sends a car rolling over a couple times will have a much lower Delta V (and therefore less energy transferred into the occupants than a crash which instantly stops the vehicle at the site of the crash. The crumple zones in a modern vehicle are just an engineered way to lower the Delta V by extending the distance and time required to smash a crumple zone and expending energy there rather than sending it into the occupants. A crumple zone might be 24” long. That’s all the distance that can be used to expend that energy. A rollover might use 40 feet of distance to expend that same amount of energy as the crumple zone, over a much longer timeline. Therefore the rollover will have a much lower Delta V

Because SCIENCE!

DP. But doesn’t rolling increase the risk of being ejected from the car?   Maybe not, I’m not a scientist. [/quote]

If you’re not wearing a seatbelt, yes absolutely.  But if you don’t bother to wear a seatbelt, you don’t even belong in a conversation about safety. [/quote]
