Batman's The Bat was destroyed, but there were others.
And even when that snippet in the picture wasn't shown, we do see a glimpse of another vehicle next to The Bat that Bruce Wayne will end up using. (at 1:16)
What those men are checking is the patch of software, or hardware even, that makes the auto-pilot work and that was fixed for the other "Bats" as well to show Lucius that Bruce is indeed alive.
