You are arguing semantics and aren't even right about it. A drawback can be minor or major. We are in agreement but your being silly about the words I use even though they are completely valid. You might want a synonym that's harsher but that doesn't make the use of the word wrong.

I'm basically saying it's a problem and you are going "no fool, it's a really really big problem", like no shit, that's what I said. I even added the word clear to show that's it's not a small drawback but a major one.

It's all the same type of software that would be used and it would sometimes break randomly for no clear reason no matter the use case. Why would they tackle detection differently between being on the highway, on a residential street or on a street in front of a house? The same edge cases would apply to each (like billboards or faulty GPS signal for example).
