Playing GTA V hasn't come without it's share of WTF moments. For example, I've found in high speed chases even in single player mode lags as if you were playing with a bad internet connection. I clip through the car I'm chasing way too often.
Some other times I'll drop off a cliff that's no higher than 15 ft and end up with my car exploding on imact. That's really annoying. The first time it happened to me I did shout "WTF!?"
And let's not forget...
Go ahead and share your WTF moments. I'm sure you've had some.
