My favorite case so far of the '5%' that you mention happened on my Tesla irt:(object recognition) and I still laugh about it to this day.
I was driving down the road as normal, 4 lane divided highway that's a bit hilly. Suddenly my car starts having what I can only describe as a panic attack saying I'm running a stop sign and blaring alarms.
It was detecting a giant 40ft tall red circle sign a bit away as a stop sign...
That's interesting, because my car never has blared an alarm for that. I live in a part of the country where, in certain parts of semi-rural and hilly areas, they've decided to introduce 4-way stops instead of red lights, or to slow down traffic on a straightaway. As a result, every so often I would not realize there's a 4-way stop (luckily google maps now shows them) and stop a little late. This happened 2-3 times in the last year or two and never did the Tesla make a peep.
Replying to my own comment because I just remembered this as well...
I definitely saw a case of them overfitting their neural networks lately.
Going over a single lane bridge that's an exit ramp, the car started decoding the "other side" of the concrete barrier as oncoming traffic lanes...when there was nothing there.
