...another variation on this would be an emergency water cooling port. Like you have a fixture somewhere on the car that you can connect a hose to and it runs water through coolant channels. A lot of EV batteries have something like this already, you'd just have the ability to run external water through it instead of just going with a closed loop. You'd also need an outlet, which I guess would spill ethylene glycol all over everything if it wasn't contained, but better that than a burning car.
