Electric you can use the batteries to add storage to solar panels. Most home solar installations rely on the grid for power at night and sell excess power to the grid during the day. So to make it self contained you need lots of batteries.

In the Aussie outback there may well not be anti-freeze. Just rust and anti-rusting compounds.

For that matter, it's an electric car.

There is so much useful stuff it's hard to know where to start.
- Batteries, for the sulphuric acid and the lead as well as the other uses mentioned so far.
- solenoids, alternators, fuses, spark plugs are all generally useful.
- Diesel engines are potentially useful power plants, especially as stationary engines. The gearboxes and belts as well.
- reversing cameras and display screens.
- airbags
- leaf springs are a decent source of steel for melee weapons.
- pumps and pipes

In an electric car you won't have those. The batteries will be lithium based, not lead based.

What would be reasonable stats for a hubcap shield? I suppose weight and DR/HP would depend on the type of cap for a particular car, but probably DB 1 in any case.

The modern Tesla actually has both. They have the main batteries that power the engines and need to plug into a wall to charge, and they also have standard 12 volt batteries that run wipers, windows, locks, displays, and all the other parts ICE cars already use electricity for.

Are electric car motors simple enough to be useful without complex electronic controls?

Pretty sure at the base it's a brushless dc motor, but it's certainly designed to be controlled by a car so it would be at least a bit of an adventure converting it to another use.

Tesla's, and I think most of the modern EVs, have the two different kinds of brakes, the regenerative braking of the engine and actual friction brakes using pads. The pads last a long time, because the regenerative braking keeps wear and tear off of them.

The big motors are pretty straight forward, most of the computer stuff goes into managing the battery (I know acceleration and friction braking both work if the computers go down, as I have had that happen). Fixed gear, capable of very high RPM. Could make it run as a generator for water or wind or human power.

Plenty of people already buy damaged Teslas and pull the battery packs for use in home solar and wind installations. 60 to 100kWh, and growing. 2050's? 200kWh might not be crazy. The semi-trucks have massive battery packs, truly crazy sizes. The batteries are both somewhat fragile and fairly tough: Individual cells die to impact pretty easily, but there are LOTs of cells, so even partially destroyed packs can be scavenged for useable batteries by someone with an EE background.
