I expect them to make the case to the relevant people instead that it's a bad idea, and resist, so when the lawsuits get filed they can pat themselves on the back that they aren't part of it, because their cars weren't updateable over the air and thus aren't part of it.

Unfortunately, "the lawsuits get filed" is comfortably beyond the planning horizon of any entity out there right now, even though we're talking about lawsuits with the reasonable chance of driving the affected companies right out of business.
