If you’re using the “double-cutting” method, should you use the passenger or driver’s side windows?

Answer 1: It doesn’t really matter which side you use, so whichever is more convenient for you.    Answer 2: If you’re right-handed, it might be easier to do the driver’s side.    Answer 3: Basically, you should choose whichever side presents less of an issue while trying to work around the side mirror.
