I always cruise around on 2nd or 3rd gear. My gf likes to put it in neutral and coast.. then put it back in gear when it gets too slow & repeat. I told her that's unnecessarily using the clutch. I try to use the clutch less as possible to prevent wear.. am I being too picky?

 

Seeing it's supposed to be 10-15 MPH or less, I usually leave it in 2nd and let the revving of the engine remind me to slow down. Using the clutch pedal that much is a hassle anyway.
