Wouldn’t be a good look for that wankpanzer if a $5 tool from Walmart could bust through its windows. Better call it a Cyber-izer and sell it for $200.
Other nice options as stocking stuffers can be spread around the car, like in each door, glovebox, keychain. The hammer type you linked is easier to hold, but you may not be able to reach the glovebox.
I have broken windows with all three of these exact products during regular extrication training as a firefighter.
I don't trust the yellow one for some reason. I feel like the mechanism wouldn't work or may require more pressure than one would immediately give. The more mechanics involved, the more points of failure introduced.
I can say in my training experience the yellow one works great. It doesn't require a wind up either.
Imo have a hammer in your glove compartment for helping OTHER cars. Have the small variety near each window so each occupant has a better chance of getting out (if the front right is crumpled, the glove compartment may not open)
That's my move, but having anything is better than nothing
Another problem with some teslas (and other vehicles) is that there are switching to laminate for the side window glass for strength purposes. These devices wont work in a survival situation if your car has laminated windows. LINK
I have heard it's easy to kick out the windshield, but I've never had to test that theory.
I've tried to kick the side rear window out in a taxi driver fainting situation, it's really not trivial, particularly if you're the only one in the back.
Tempered glass is much stronger than people imagine. It breaks easily with the proper tool but without one there's a good chance it wont no matter how hard one hits and kicks it.
I have one, but the issue is being able to find it in an emergency and remembering that it's there. It's like girls I've known with a 9mm, uh, somewhere, uh, just in case. You actually have to practice some.
For example; Every time my wife starts burning something in the kitchen I get out of my chair and go to the fire extinguisher. Muscle memory is a thing.
