I think that's a misunderstanding, or a misinterpretation of what I meant. I didn't say "there is only one situation", I said "there is one situation".This could be interpreted as "only one" or as "one of many". I meant it in the context of "one of many". There's an implied "there's (at least) one situation", but without that explicitly stated, you're right that there could be an implied "there's (only) one situation".

So allow me to clarify my original post: There's at least one situation where drivers don't face penalties.

And then let me word it a little more strongly: There's only one situation where drivers, under the law, don't face penalties: when the driver was not at fault. Because the situations you listed are those where the driver legally could have faced penalties but did not.
