Does anyone know any more about this? Is it an evolution of ABS or is there more to it?

The linked video is a bit short of details.

I'm still getting my head around how slow mechanical systems are compared to the control electronics :lol:

"Real-time" takes on a whole new meaning.

Moog! Retro technology? Good luck with that one...

Cheers for the info and trivia to go with it!

There's a Moog factory just off J9 of the M5. I've always imagined the place to be some kind of museum of prog rock.

Anyway, the valves I'm talking about are these.

Cheers Dave... Some interesting and new-to-me reading to look at. Did smile that it included 'trumpet control'... Not so far away from the other Moog then..

What I need is something to control my tendency to play the bass trombone at inopportune moments: it can be most embarrassing. :shock:

Does this mean lorry drivers can now drive even closer to the back of other vehicles with a complacent sense of safety?
