I picked this product at random. Imagine if it had a detachable window hammer/seat belt cutter combo and 360° lights pointing various directions. The base could be made strong enough to be a second or even the primary window hammer in case the first one is dropped. I like the idea of being able to breath, having light and a separate window hammer.
6 to 12 minutes of air time. It could even be shared.
It's the scuba diver in me.
Overkill, no pun intended.

That is a very cool concept and worth considering.
I found an AAA article from 2019 where they evaluated different car escape tools. It didn’t mention devices by brand name but by type— the hammer type vs spring loaded. They also looked at the seat belt cutting capabilities.
The results showed the spring loaded devices are much better with tempered glass, but the laminated windows were near impossible to break with any of the consumer available tools. Many other posters have also mentioned the difference between tempered and laminated windows.
“Key Findings
6.1 Summary of Tool Testing
The results of the seat belt-cutting and window-breaking tests are illustrated in the figure below. Three tools (numbers 1, 4, and 6), two of which were spring-loaded type, performed comparatively well in both tests, successfully breaking the tempered glass while also recording fast times in the seat belt - cutting tests. Each of these tools is compact, an important consideration in selecting a vehicle escape tool. A tool should have the ability to be easily stored and accessed within the vehicle for it to be effective in an emergency situation. One of the poorer performing tools (number 3) was quite large, making it not ideal for storage and difficult to maneuver during seat belt -cutting tests.”
“6.2 Laminated Side Windows
A significant observation of this study is the noted differences between tempered and laminated glass used for side windows. It was discovered during testing that it is nearly impossible to bre ak through laminated windows using a consumer-grade vehicle escape tool. With new safety standards, such as FMSVV 226, the use of laminated glass for side windows is becoming increasingly common. Many popular automotive brands produce a model with these types of side windows. To determine whether a vehicle has laminated glass, check the window label, typically located in the corner (see figure below). If there is no label present, contact the vehicle manufacturer to determine what type of glass is installed. Drivers should know whether their vehicle has laminated or tempered windows, because, in an emergency, a consumer-grade vehicle escape tool cannot be expected to break through laminated glass.”
“This testing found mixed success with the evaluated tools. Three of the six tools (two spring -loaded and one hammer) performed well in both glass-breaking and seat belt-cutting tests. This testing also has shown that consumer-grade vehicle escape tools are not capable of penetrating laminated glass. For this reason, motorists should be aware of the type of glass installed on their vehicles, tempered or laminated, for side and back windows. To do this, check for a window label, typically located in a bottom corner of the window. It should indicate whether the glass is tempered or laminated. If this information is not included in the label or there is no label at all, contact the vehicle ma nufacturer. Some vehicles are also equipped with different glass material at different locations in the car (i.e. front side windows could be laminated but rear side windows could be tempered). Provided in the appendix of this report is a list of vehicles sold in the U.S. equipped with laminated glass. However, the type of glass used can depend on trim level, so it is important for drivers to inspect their personal vehicle to be sure.
If a vehicle does have tempered windows, AAA recommends having an escape tool in the vehicle at all times. Drivers should choose a tool that they are comfortable using and that can be securely stored in a location in the vehicle that is accessible after a collision or accident has occurred.”
“Vehicle escape tools come in many varieties, but it may be best to avoid a tool with extra features such as lights or chargers since these functions do not improve the performance of the tool itself. A vehicle escape tool’s sole purpose should be to aid occupants in quickly getting out of their vehicle in an emergency. It is important to note that, in the event of a submersion, a hammer tool could be much harder to swing due to drag the water will exert on the person’s arm when trying to swing the tool.”
I found this very helpful and hopefully the source , AAA, is acceptable.
