It's all about situation awareness. If you have that, chances are great that you'll be fine. I drive a nice car, and my office is in a crappy part of another town away from my residence. I'm always aware of a possible car jack attempt, the bump and jack attempt, hazardous situations, or getting cruised by the crack zombies on bikes or on foot. Stay alert, stay alive.
Great article you dont often see articles about this topic. I would add that when the road is blocked by a mob that you can gently push through assuming you have a full size vehicle (a 4x4 will always be better). Do NOT ram them with speed as most modern vehicles have a collision shut off; but just putting the vehicle in drive will cause enough momentum to motivate the crowd to move. Remember you are in fear of your life as the car is surrounded by violent protestors.
I also suggest having mob/riot control gear handy. Amazon sells PEPPER GRENADES (think the pepper spray on your wife's key chain, except that once the tab is pushed it locks the tab open and dumps the contents. So crack your sun roof and toss out the can. Paintball smoke grenades arent especially effective for concealment (at least not on a military level); but they are relatively cheap and add to the confusion of the Pepper Grenade. IWI sells distraction devices (think stun grenades but not on the level of PD grade devices). They are available in single and multiple "BANG" units. Having a gas mask handy isnt a bad Idea either. After all that I'll let you decide if you want a high capacity weapon, think AR/PCC OR something like a Tac 14...
