Window up or down, whats better in a crash.
This is a question I got from Twitter, so, what do people think, what is better.
Is it better to have a window open or closed if you are in a collision?.
If a window breaks, you will get flying glass, especially in older vehicles without modern laminated glass, is all the flying glass better contained in the body of a door with the window open, or is it better to have it closed to prevent intrusion by other foreign object FOD and the like?.
My own choice?. Better a closed window that "May" prevent FOD than a face full of tyre thats flown off a passing vehicle.?.
And then there is another one that I sort of remember from the past as well, a partially open window that doesnt have the support of the door frame to the top and front edges [dependant on design of window and how it opens} is more liable to break from impact than a fully closed window.

I'd be more concerned about the window being shattered by my head, not a flying tire. In that case, it would be better if the window wasn't there.

I've been spattered by window glass, and it's not that big a deal.
my personal take: it's about the same as "did he have on clean underwear?" "not when we got to him."
odds are, by the end of the crash, your window will be open, and if it isn't, there's a good chance, we will fix that oversight. only exception is if it is so minor you can open the door and get out.

When I attended the FDIC fire show last month, it was amazing how many different companies were showing their version of "Jaws." The only difference was whether you wanted one powered by a converted Milwaukee, Bosch, DeWalt or Ryobi cordless drill. |

I recall early in the electrics tech, a vendor though he had a winner with a 18V sawzall powered by a cord connected 12V lead acid battery pack. wonder if he has figured out yet why we didn't buy one? to be fair to him, we didn't pull up an engine next to him and fire up the inverter to have a side by side comparison of corded battery or corded inverter powered sawzalls. |

Another thing at the show was an over abundance of battery powered smoke evac fans. In fact, I was kidding with some of the guys in our booth that all we need to do was take one of our 18" condenser fans and hook it to a Li-ion battery pack and we'd have a new product. |

I have been a philosophical opponent of gas powered positive pressure fans ever since I read an article recommending that people run one in a training structure for a while and then take a gas analyzer in to see what it was actually filling the building with. hint: the exhaust is directly upwind of the fan. |

If the car is sliding on its side, this would give you a very nasty road rash in the face... Well, I have been in a car that had rolled over. I was glad that I had bruised my elbow on the window rather than have the arm stick out with the car rolling over it. One of the first things you learn how to properly race a car is that when you loos control, stomp the brake pedal as hard as possible and lift your hands and press them against the ceiling. That way your hands won't be broken from the steering wheel nor crushed when pushed out of the windows by g-forces. |
