Other mistake: The configuration of the front side of the house does not match the configuration from the inside. The outside view looking at the house from the street indicates (1) there are no rooms to the right of the garage (when inside there are rooms on the side of the garage). Also when looking at house from street side, to the left of the front door the house comes forward. When inside, (at least in episode 13, season 3) the inside of the house does not extend forward towards the street.
Other mistake: Walter's pants flying in the air defy the laws of physics. The RV is racing forward and the pants somehow find themselves in front of the RV floating through the air. One could say that the pants perhaps flew forward when the RV 'hit a bump' perhaps. However the RV would have to hit a considerable sudden stop to get the pants to fly forward. The RV then runs over the pants which have fallen to the ground from in front of the RV. This could be ignored as somehow possible due to some strange anomaly. Except near the end of the episode. We see the same pants fly off the mirror of the RV flying backwards. Making it impossible for those same pants to be run over from in front of the RV especially due to the speed at which they are flying backwards straight into the camera shot.
Other mistake: When Walt is ringing Jesse to find out where he is, the call goes straight to voicemail. However, when he rings Jesse from inside Jesse's bedroom, the phone rings before going to voicemail. The mistake being that the call should have gone straight to voicemail.
Other mistake: At the end, we see the gunfight between Tuco's cousins and Hank. Several shots are fired, cars smash into each other, a woman runs off screaming. So not a "quiet" attack. However, as the camera zooms out to show the carnage, 2 people who are not involved in the attack, are just stood talking in the car park. A bit odd since there has been a very clear shoot out.
