This brings up a similar question that I have. My son took over driving my
'97 Civic and when he's rolling down hills, he engages the clutch to "roll
in neutral". I have told him that I didn't think this was a good practice
but can't explain why it might be bad for the clutch. Can someone explain
for me: 1-is this bad for the clutch? and 2-exactly why?
Thanks,
