Car windows are probably harder to break than you think...lol. Also - consider the situation where the car is in, or partially in water, and pressure differentials.
I keep a Resqme in the car glovebox - my other half used to do a lot of interstate driving, and I was always worried she'd be trapped in the car. The Resqme has both a seat-belt cutter, and also a centre-punch for easily breaking the side windows.
This is a genuine question: how useful is the resqme in a glove box? Do you think the driver could reach it in the event of an accident, or do you keep it so the passenger can use it to free the other occupants?
I'd clip it to the seat belt pulley. But round here you'd have difficulty reaching speeds to have a crash, what with all the minis doing 20 under the limit
(There was actually another HN thread about this recently - https://news.ycombinator.com/item?id=39691780).
