The far harder problem was dealing with the sensitivity of the radio

That's a different matter from the topic under discussion.

For example, on a tank, when the turret was rotated, one could find
sharp rising spikes of 600-800v on some of the wiring.

So you don't use that wiring as pickup points for accessories.

I suspect that in a typical domestic car and possibly even a commercial
truck, the potential for problems is not as great and certainly
electronics has been improved from the EMC perspective over the last
decade. Nonetheless, the mechanisms for bad things to happen are
certainly present in a motor vehicle.

What you're implying is that laptop makers who supply leads for car use
are unaware of this?
