If one of those cars did it once, then well, it's a spare change for you. Doesn't matter if the grand scheme of things. If one of those cars is involved in its third DoS happening in the last quarter, you may be able to alert the authorities while it's still charging. You can fail safe with your failsafes. You can react differently based on different kinds of failures. You can put limits to how generous you want your failsafe system to be. You can have an independent killswitch for your failsafe mechanism. You just need to put some effort into designing your system's failure modes. You may also find out that DoSing the charging station in order to use it for free simply doesn't happen in the wild and that you can safely afford to only react once you notice it actually happening. That's why you pay all these security engineers that are able to reasonably assess these risks, you know.
