I've been pretty big into preparedness and all the corresponding bug out bag stuff.
Here is my practical experience for what it's worth.
1. It is fun to research all the gadgets and toys, but most are impractical to lug around.
2. If its not on your body or within 5 feet at ALL times you probably won't have it when you need it.
3. Bug out bags generally don't work if they are not regularly used. Batteries die, light bulbs break, etc.
I've revised my solution several times and here is what I do today.
1. Have a point and shoot 4x4 as a daily driver. This will pretty much be in the parking lot of wherever I am and can get me into and out of most anywhere. Keep the gas tank more than half full.
1a. Keep necessary tools an spares for repair in the truck (ie belt, headlights, fuses, wrenches, screwdrivers, etc) This can be done pretty weight effectively if you find a good compact tool kit and bring only what you need.
1b. Keep survival gear in the truck up to date, check each month. For me this includes but is not limited to a hennesey hammock, freeze dried food, kelly kettle, compact sleeping bag, knife, lighter, matches, complete first aid kit, firearm, and ammo. This all fits in a hardware store plastic tote in the back of my jeep with the exception of the firearm.
2. in my work backpack (swiss gear) keep meds, light first aid, knife, headlamp, gps, fire starters, water purification, and mini dopp kit, spare batteries. This is VERY compact. This is with me at work and just about everywhere I go. It is low key and untactical looking so it doesn't draw unecessary attention.
3. I keep cash, but I won't tell you where. In america, this is THE BEST survival tool.
I try to use and replentish both kits regularly to keep them top of mind, and familiar. I use them both regularly including shooting and lubing the guns.
