Best thing is vigilance and common sense applied liberally. I have LEO friends that tell me, "...nothing good happens after 1:00 a.m."
Of course, they are speaking about "outside".
So, my guess is that ANY vehicle, parked next to a downtown bar at 3:15 a.m., is at a higher risk for theft (or ???) than mine sitting i
n the driveway, parked there 365. And almost ALWAYS there before dark.
Having said that, I have a power cut off to the fuel pump. It'll never "tick" unless I tell it to.
And the switch is in a very strange place.
