Agreed. If that's your goal, you could prepare an extension cord with appropriately-sized alligator clips [1], so you could hook it up to any car battery directly. You'll need to keep a roll of duct tape around so you can insulate the clips once you've attached them.

1: e.g. the ones found on jump leads.

Unfortunately my entire plant draws just a little too much for the cigarette lighter plug, probably 15 amps total. If I could invest in new phones / new servers / etc and ...

Your car can easily supply 15A. It's just the crappy cigarette lighter plug that can't handle that load. It's pretty simple to add a custom power socket to your car though.

If you do this, do get some heavy-gauge wiring to run from the car to your servers. At 12V, wiring losses add up, and cabling can get pretty warm if it's not thick enough. .

In additions to the reasons already mentioned, keeping a big, heavy turbine running at 50/60 Hz in an earthquake is likely to (violently) destroy the turbine.
So you need to stop the turbine, which means you've got to stop producing steam. In case of a BWR, the steam is radioactive so you can't vent it so you have to scram the reactor.

The most compact nuclear power plants around (naval units used in submarines) weigh about 1000 tons. These use highly enriched uranium, so they would be seen as a security risk.
Containerizing this unit would mean at least 50 40-ft containers (with each container at its maximum weight), you probably need more because most containers won't reach this density. That would give something like 80 MW. Considering that a 20-ft container can hold at least a 1-MW diesel generator with its fuel supply, having a containerized nuclear reactor would seem to hold little advantage over diesel gensets.

There's also the problem that you really want the reactor vessel and the primary coolant loop as one unit, since you can't easily disconnect these once the reactor has been active and has irradiated the primary loop.
Now the reactor vessel alone is larger than a standard container. You'd end up with a very large and heavy undivisible central unit.

You'd be better off leaving the reactor on a ship and just running a cable ashore. For smaller power needs, existing containerized diesel gensets are a good solution.

Over here the LifeHammer (and its copies) is popular. It's a small plastic hammer with a pointed metal head, purpose-designed for breaking windows when the car is under water. There was a Mythbusters episode on escaping from a submerged car; both the auto punch and lifehammer worked well to break a window. Note that both need to be used on the side or rear window! The windscreen is laminated and you'll only break the inside layer with these tools. Side windows are tempered and will shatter.

but I don't want to be in a road train inches in front of a semi when its tire calls it quits.

That doesn't make sense. Being in front of the semi, there's no way it'll hit you when its tire blows. If you're behind it, the computer will notice the semi slowing down and will brake accordingly. Speed matching and collision avoidance is in production cars today, and works well.

The only remaining hazard is tire debris. I think we'll see mandatory tire monitoring systems before we see automated roadtrains, which would mostly eliminate that hazard.

Brake failure needn't be a problem in a road train either: because the cars have very little separation, the speed difference will be small, the failing car will bump into the car in front (after giving a warning through the intervehicle communication system). The car in front can then help bring the failing car to a safe halt.

Total brake failure is very rare, though.
