About clutch riding, that's logical as well, I suppose, I was trying to point out that it wasn't damaging, but there isn't really any reason to do it either.

1) Alright good point, haha, when you put it that way it kinda does make sense, probably should have thought about that a bit more.

2) That's what I actually meant, don't use gears to slow down ridiculously slow. Like sure, you can use them a little bit, but don't be going 100km an hour and slam it down into second gear, try and be close to the "Sweet spot" at you said, by either slowing down enough with brakes first or rev matching, it's going to easier on the gears and more comfortable a ride.

It's all simple math on knowing how slow you need to be before going to the next gear. Any gear calculator will tell you the maximum speed of each gear. If you're not slow enough, then bad things are obviously going to happen.

Example from this calculator with my car's gear ratios, tire size, rev limit, etc.

225/50R16 tires (24.86" OD)

3.25 final drive ratio

Rev limiter starts to cut in at 6k. Fuel cuts at 6200.

1st gear - 3.822 = 36 mph @ 6000 rpm = 37 mph @ 6200 rpm

2nd gear - 2.203 = 62 mph @ 6000 rpm = 64 mph @6200 rpm

3rd gear - 1.398 = 98 mph @ 6000 rpm = 101 mph @6200 rpm

4th gear - 1.000 = 137 mph @ 6000 rpm = 141 mph @6200 rpm

5th gear - 0.812 = 168 mph @ 6000 rpm = 174 mph @6200 rpm

Therefore if you're under the road speed where you're rev limiter kicks in at in a gear lower, you can in theory downshift to the next gear (though depending on which gear, the force of compression and gearing working at high RPM's might damn near throw you windshield ). Rev-matching (or bumping/blipping the throttle) will obviously make each downshift a little easier. That's also the way to shift without using the clutch. Though if you do downshift at a high speed for the gear under, I'd recommend using the clutch as you can at least feather it a bit to lighten the initial shockload somewhat. Though, midway through the RPM range is definitely gonna be most ideal here for normal driving.

I am confused, I always thought "riding the clutch" meant having the clutch pedal partially depressed, but I guess not. Let me check:

RIDING the clutch = keeping the clutch pedal fully depressed disconnecting the engine from the wheels completely AKA "coasting"

FEATHERING the clutch = partially depressing the clutch pedal for hill starts etc.

This what sivis appears to mean but lurch is using terminology how I thought originally.

That isn't really what I meant. Coasting is distinct from riding the clutch, but you still don't have any proper control when you are riding it because "riding the clutch" implies feathering done badly or unnecessarily. It's a partial depressing of the clutch in unnecessary circumstances, for prolonged periods of time or otherwise in ways that are detrimental to the control of the car.

My mate held his car on an incline with clutch partiality pressed to hold him still.
He only did it for 10 seconds but we could smell it as he took off.

I don't know if that was due to him holding the car there, or because his 1.7 ton car currently weighed 3.8 tons including trailer.

Probably holding it for 10 seconds there. There is really no reason to use the clutch to hold you for anymore than a second.

I learned that lesson the expensive way.

Except that I didn't. Habits die hard.
