I've seen a few posts like this. I can't confirm it still existing, but if it does It might only be fixed after the EU
The server knows the player's location, the client displays it incorrectly. From Shini's video it looks like it was failing to keep up with the server, possibly due to an animation issue offsetting the player's visible location, but smoothing a kind of location transition to catch up with it. Maybe the 1-frame thread lag causes this?
EDIT: If you can hit them in their "incorrect" position then the server is at fault for the incorrect location, despite being pushed by the car, being illogical... Nonetheless it might be something very odd server-side.
