Visible crew/equipment: When Han does the handbrake turn right at the start, you can see the camera car reflected in the chrome bumper in the closeup. Slo-mo helps but is not required. There are also skid marks from previous takes. (00:02:00)
Visible crew/equipment: Just after Dom says "T, you're up," a camera moves across Han's truck and up to the window. When it moves the shadow of the camera can be seen on the orange paint, moving. (00:03:00)
Visible crew/equipment: When the guy on the roof stands and takes aim at the window in preparation for Brian, the film crew are reflected in a window behind him. (00:13:00)
Visible crew/equipment: After Brian transfers Mia in the FBI building, there is a shot of a red car with chrome bumpers. In the bumper you can see a cameraman walking forwards with the camera. (00:24:15)
Visible crew/equipment: When Brian steals the Humvee, and stops for Dom to get it, there is a camera very prominently reflected in it. (01:01:50)
Visible crew/equipment: When Brian at the end says "don't make me laugh", if you look at the chrome bumper of the green Torino he's leaning on, you can see a member of the crew moving. It's not Toretto as he's on the other side of Brian, and it's not any of the Police as evidenced by the following shot that still shows them to be far away.
Answer: No it doesn't ignore 2 Fast 2 Furious, Brian even references it a couple of times. In that movie, Brian was promised a 'clean slate' if he helped them out which presumably gives him the option to rejoin a law enforcement agency. That he chose not to open a garage with Roman is pretty much redundant, Brian simply got a better offer, and as he stated in Fast & Furious with his conversation with Mia, "I'm a good liar".
