I have two trauma kits in my car which include chest seals, Quick Clot bandages, and a SWAT-T tourniquet. If you pack it right it’ll all fit in an 8x6x3 kit.
One is loose, the other is packed in my “Go” bag. There’s a few other goodies in there as well.
Doesn’t take much to put one together. Learning the skills to use them properly isn’t that big a deal either.

Have a zippered bag about size of hand, was a travel bag for laptop mouse. Has gauze, gauze squares, (2 x3 inch), triangular bandage (folded), tape, mini swiss army knife, safety pins
Keep it in glove compartment in car......
Plus the other EDC stuff that may come in handy in a similar situation.
Better to have it and not need it than need it and not have it.
