Need I press clutch pedal while starting my car in neutral?

Being from Canada, I feel compelled to mention that if you do not depress the clutch while starting when it is at all cold out (let's say < 0 Celsius) you will notice the starter motor labouring ...

This is common among all motorcycles that have a "wet" clutch system. What that means is that the clutch is surrounded by fluid, usually engine oil. Even though you have the clutch pulled ...

Clutch smell after botched attempt at accelerating on a ramp

If it was just once, I wouldn't be overly worried... particularly as you say the car is driving fine. You took a bit of life off your clutch, and I'd keep an eye out for issues in the coming weeks ...

What happens when I shift gears without pressing the clutch in a manual transmission while the car is running?

Does rolling forwards while in reverse gear damage my car?

Absolutely not. There's no issue here. The engine/transmission were not coupled. There was no stress on the transmission. It just was running backwards from what it usually would. Really, it's no big ...

Should I depress the clutch pedal when braking to a stop?

Is it worth replacing the entire clutch assembly when the clutch release bearing fails?

At ~110k on the clock it's quite likely that it's the original clutch, and if so you're going to be significantly closer to the end of the clutch's life than the start. Given the big labor cost/...

What would happen if you shifted into reverse while you are going forward?

My theory is that the engine would be forced to rotate the other way around, wouldn't it? Then, because of that, the engine would stop, and therefore it will "generate" a lot of force to the ...

Why don't cars have multiple disk clutches as motorcycles do?

It all comes down to size. There is one thing which makes a clutch work, whether wet or dry. It comes down to friction. There are two ways to achieve the friction needed to transfer the energy from ...

Clutch smell after botched attempt at accelerating on a ramp

This happens all the time at autocross events, in extreme cases the clutch will get "glazed" and slip a lot until the burnt material is worn off. Since you aren't having any trouble, you'll be fine.
