You're welcome.  Note that single-clutch computer-controlled
gearboxes have been around for a while (I've got one in my Z4),
and are still what is used by Lamborghini.

Especially since you need to replace the whole setup every 200 miles,
not just the pads, and they don't come cheap :-)   Actually the brake
technology is one of the hardest things to come to terms with on F1
cars - even a reasonably competent amateur (such as, say, Richard
Hammond of Top Gear) can't exercise the brakes on an F1 car hard
enough to get the brakes up to temperature, so they hardly work;
that's another thing that would keep them out of consumer models.

I didn't know what you were looking for, so I lasted one bleeding-
edge technology, and one more mature (and more practical) example.
