What do you carry around in your car?
I have spare tire, flares, pens pads pencils, water, firstaid kit (have CPR training), towels, blanket, airpump,fuses,tape, pliers (and other simple hand tools), tow strap with shackles, windshield cleaner, california duster,..., uh..., and other stuff I can't recall at the moment.
Anything to add? We want to be comfortable, safe and have convenience for ourselves and our passengers, right?
