Redundancy is a good thing. I have a car bag, I have my BOB, and they usually both end up going with me. The car bag includes some items I would not carry in a BOB, such as umbrella (nice to have if sleeping in the car so you can keep window open and keep rain out) and more maintenance items. There is also water and food in the car at all times, which gets pulled out and used on camp outs and replaced afterward. first aid/trauma kits in BOB and car at all times, and get checked and resupplied once a year, and inspected by professionals (EMT, RN, PA friends). Each family member has their own BOB with trauma and first aid kits. BOBs stay in bedrooms while at home. Each family member also has a small or medium size duffel ready to be loaded with extra clothes.
