The fact of the matter is any opposing force will be looking to disable your vehicle to take what you have up to and including your life. Having to protect newer model vehicles electronics or looking for an older vehicle without them for fear of an EMP is really not even a valid argument. The most likely SHTF scenario will be a civil social uprising pitting fellow citizens against one another. So unless you have the money, time, and skill to either buy you a armored vehicle that can’t be stopped, or build one, everything else is a bullet to the radiator or a spike strip to your tire away from you being involved in an incredible two way rifle range ! The best you can hope for is a spouse who can drive and DRIVE WELL and or shoot while you DRIVE WELL or your life expectancy is going to be that of a WWII tank crew, maybe 2 1/2 minutes. Best you can hope for is to link up with a platoon size group and beat feet it to a safe zone.
