One the one hand, "hydroplaning" is another word for "aquaplaning" so you were wrong to correct OP.

But, on the other hand, the message being conveyed was clear enough that you knew what they were saying, so you were wrong to correct OP.

But, that said, on the other, other hand your tone is just gratingly smug and, even if your actual point was valid (to reiterate: it wasn't), based only on your condescending manner you were wrong to correct OP.
