There is nothing passive aggressive about speeding up when being passed. The previous behavior of going too slow is what was passive aggressive; but once that driver accelerates, they have disrobed themselves of all pretence of passivity.

That might be true but only if we know their motives, which we usually don’t. One could argue that any driver isn’t passive aggressive because they are actively driving their vehicle. However part of the passive aggressive definition includes intentionally making mistakes in response to others demands. All of that being said, the difference is subtle and probably not worth arguing in this context.
