Good thread subject!
I learned to drive clutchless 30+ years ago, from my taxi driver boss. I had a fare in the car when the clutch went. They sent another car out for the customers, and the guvnor arrived a few mins later and drove us back to the garage. After I had watched his method it was easy.
As James says, stick it in first before you start the engine.
Turn the key and steer with the other hand for a couple of seconds, a tiny bit of right foot will see you moving nicely. Watch out for kangaroos!
Once you're moving, and aren't accelerating, you can take the gear lever to neutral and as the revs are dropping, a light pressure by you against the next gear position will usually allow the lever to slide in usually without grinding. Usually! Don't worry if you allow the revs to drop too far, even down to idle, while you're moving, just back off any the gear lever pressure, rev the engine up a bit, then re try the gear as the revs drop again. You can even do this if the car is going slow enough for first gear.
Once you've done a couple of smooth changes you'll get the idea.
When you want to change down, take it into neutral, rev the engine up a bit and light pressure against the next gear like before, but while the revs are higher, will usually allow the change.
You should be able to roll up to junctions during the drive, by just knocking it out of gear. Engine off, if you have to stop, into first again, wait for a good gap, turn the key and carry on.
The V6 is the best engine for smooth clutchless driving by the way. 2nd gear will pull from about 2mph to 60+ !

So if you're planning on having your clutch blow up, get a V6 first.
