The SMG is a tremendous transmission. Responding to some specfic questions...
1. You can modulate the shift speed of the SMG by feathering the throtle as you pull the paddles or shifter. Even in the S5 mode which I drive in 95% of the time, it is easy to shift very smoothly. SMG's shifts are controlled by the rate of acelleration as well as the mode selected.
2. Your left foot does not get bored. There is a dead peddle that it can rest on.
3. Instead of having less control SMG gives the driver more control. Pushing a clutch in and out, having to heel and toe, as well as being concerned about a possible miss shifts at the limit of RPM's are no longer a concern. I can now keep both hands on the wheel and concentrate on the road and the turn ahead.
4. There is an idicator on the dash below the tach. that clearly tells you what gear you are in. It is plenty large and if you are unsure a quick glance as you check the tach will tell you.
5. The down shifts, with the computer controlled throtle blip and rev matching double clutching, are simply addicting and they're perfect every time. Myself and others have commented that this my be the best single feature of this tranny.
6. I seldom use the auto mode, but if I'm on the phone or my right hand is otherwise occupied it is very nice to be able to quickly push the shifter to the right and let the computer do the shifting. Once the call is over, an addtional push to the right of the shifter or a pull on the paddle and I'm back in S5 mode.

For those of you who have never driven an SMG M3, the learning curve is very steep. You can become comfortable behind the wheel in less than 1 hour. However many hours are needed to master this transmision. Remember just how long it took to get good with a clutch?
