Continuity mistake: Prison scene - Jason Statham jumps over the first rail and lands with his right hand on ground. He would have rolled over his right shoulder, but when it cuts to him he rolls on his left shoulder. Next rail he jumps over and right when his feet hit the ground his bracelet is on his left wrist, but it's previously been on his right.
Continuity mistake: Near the end, the Russian chase vehicle fires a grenade at Hobbs' vehicle. The tube on the top far right is used and can be seen open. When that same vehicle goes for the second shot at Hobbs, the tube that was used before is unused now. When Dom hits the vehicle shortly after that there is a very close shot that shows that despite having just fired another round the array of tubes is again unused.
