Having recently moved jobs I've now got a commute which involves 5-10 minutes of sitting in slow moving traffic. I've gotten into a bit of a habit of ignoring the accelerator in traffic, just gently easing off the clutch in 1st and letting the car roll along on idle revs (she defaults to 4mph in first, 8mph in second), dipping the clutch again if traffic in front stops.
Now it seems to work okay, as long as I'm very gentle on the clutch. But I wanted to know if any damage can come of either the time spent on the clutch (it's a little longer than I'd spend if I used the gas, but with lower revs, so I suspect wear will be similar?) or on the engine by forcing it to pull at idle revs (ie just above the stall point).
