A NZ company has developed a "new replacement for synchromesh.
The new device provides seamless shifts with improved acceleration,
economy and emissions"

There's a "How it works" animation

Footage shown on TV last night showed a drag between two
performance cars (Mustangs), one with a conventional gearbox
and one with a Zeroshift. The Zeroshift won because there was
no decceleration between gear changes

Gears are button-selected, not flappy-paddle. I don't know
how similar this is to race-car pre-selection
