Oh, indeed. Didn't think of that!
They are showing OK, it's a 2 sided card with SOS/OK on different sides.
they are showing other side of that SOS sign
Imo it was a huge mistake, he was so much faster in that corner than anybody else. So much speed that the car refused to turn.
Why are the showing SOS sign? Shouldn't they stop then? SOS and OK have quite different meanings you know...
