I can't verify this But it makes very good sense to me, that in some contries A life Hammer is required safty gear for each auto. Not only is one required (kinda like a jack)but rather two are required, one in a glove box or accesable to the driver, and one in the wheel well of one of the rear tires. THIS makes sens so that if you rush to help a person who's car had slid into the watter.

I will say that having mutiple ways of opening windows is always a good idea. But I will add that keeping a marked window opener outside your vehicle is like putting a sign "steal me" on the car with keys attached.

I keep a CRKT MAK with seat belt cutter. in the map pocket of my door, and I also have a folder that has the window breaker. and YES I keep work gloves in may truck as well. While it is cool to keep the MAK in my truck in the map pocket in my truck, it is nerver racking when I have my truck cleaned, already had to replace it once.
