'cos car electrics are dc

Except for Ford model T.

Is there any fundamental reason why early pre-electronic car electrics
were DC and not AC?

Yes.

to go further, the car electrics rely on a battery - this inherantly a DC
device.

They need not rely on a battery. If, for example, you have a starting
handle and carbide lamps.

The T was handle start, carbide lights, magneto ignition & no electrical accessories. But it still needed a battery, the magneto couldn't generate a spark at crankhandle speed.

Start sequence:
Switch to trembler coil ignition
Crank
Switch to magneto ignition
- Or shout for assistance if it just ran you over.
