Continuity mistake: Mike's car is not visible when Walt breaks into his own backyard. Mike is still there, as you see him hiding behind the corner, and later getting into his car.

Continuity mistake: Just after Hank crushes Leonel's legs by backing into him, Marco starts shooting into Hank's Jeep. You can see Hank crawling into the rear seat to escape through the side door.
