Typical car battery is about 50amp-hours. to discharge to zero in 30 seconds requires a 6,000 amp load. if we're just pulling the top 20% off the battery in 30 seconds, it's still a 1200 amp load.
A laptop pulls 4A at 12V. Cameras an amp or two tops. Printer --- I actually don't have a clue there but let's call it 4A assuming it's an inkjet. 2 laptops, a printer, 2 cameras = 14Amps. no need for lights while refueling. Battery can sustain that load to 3 hours to zero. Lights WILL drop a battery quickly, so if they are on that's a whole different story.
I think the big argument is (in)convenience vs real world risk. I am a fan and supporter of LEO. I'm glad we have them (y'all) so I'm not gonna harp or complain. But I'll credit LEO and FD and any other real-world job being comprised of human beings who have on days and off days just like anyone else. Anyone can be a victim of a mistake.
Real-world statistics? I don't think the flash-fires are common. And less so in areas that stay humid. It's pretty rare bit obviously it happens. We can debate "real world" vs "I'm more careful" vs "incident rates" all day long, but in the end it's just a risk with a set of factors. Heck, LIFE is a risk with a set of factors.
The chances are low that it's going to happen to you. Adopt a risk factor and the chances go up, though still remain statistically low. So in the end, it's all about how many factors has someone stacked up, AND does the dice go unlucky in one particular moment.
Makes it very difficult to establish "rules" about what one should and should not do.
If it takes 3 minutes to boot the car, I would consider that a PITA. having to refuel daily with a 3 minute boot period would probably get on my nerves. There are times when I was younger that I'd leave it running, and I was just a normal Joe gassing up 1-2x per week.
Then I experienced personally how quickly gas vapors ignite doing something stupid while trying to clear brush. It happens so quickly and with such force that you don't stand much of a chance if you are near.
I shut my car off now. Happier to reduce my risks
