I usually have my PSK on me. It instills the habit of keeping it 24/7, even though I hardly anticipate fishing on the Los Angeles freeway. I'm out in semi wilderness enough to justify it. My car has several items for emergency also. Actually, an urban kit can be assembled too. I am always using the photon2 at night, producing a bandage ( plaster) and prep pad for someone's minor wound or using my button compass to confirm directions.
