"... when it comes to survival, I think of "backcountry", "wilderness" and "8-hour drive fishing trip with nobody around". I am not too concerned by urban survival."
Statistics say that most vehicular accidents occur near home. Most backcountry trouble comes from you're own ineptness (if that's a word). In the city, you are at the mercy of idiots, drunks, terrorists, thieves, poor construction, and people who just aren't paying attention.
Just a few days ago in my little one-signal-light town, a man decided to commit suicide, tanked up on booze, then got into his car and slammed the accelerator to the floor. I guess some of the poor people saw him coming at them and just couldn't get out of the way. He hit one slightly off-center and careened into another one. His front axle and one wheel flew about 40 feet into the air and came down right through another (occupied) car's windshield. His momentum kept his car kept going another 350 feet, & when it stopped it burst into flames. Three dead, more injured.
WHERE you are doesn't make a bit of difference. You usually won't see it coming in time to get your gear from home.
