LPT: Add a window punch and a seat belt cutter to your car's Keychain. Just might save yours or someone else's life in the aftermath of an accident.

Depending on the severity of the accident, the door may be jammed shut and the car's electrical system could potentially fail, leaving the driver unable to roll down the windows.

Nice to have the peace of mind knowing you'll be able to quickly break the side tempered glass if you found yourself or someone else trapped in a burning car. Here is the best 2 in 1 device imo (weighs less than an ounce)

Edit: For those doubting the usefulness of such a device, you should be aware that there were 174,000 highway vehicle fires within the United States in 2021 alone.

Better to have one and not need it than need one and not have it imo.
