In the four-way split screen, the pavement is wet outside of where Michael is, and Ryan's car is wet as is the pavement where he is. All four scenes are lit as an overcast sky. When it cuts to the next scene of Ryan's car speeding off from an intersection, it is sunny outside, the pavement is not wet and the car is totally dry.
The police have already recovered the files from the crash. Breaking into the office after that happened wont divert suspicion from Tina.
