Re: So technology works as intended...
Official figures - in the US - so are they reducing shunts on freeways - lots of cars are trundling in the same direction at similar speeds - so clearly a good use case.
Driving around UK B roads, sharing the roads with cyclists, horse riders, tractors, sheep, cows, wild ponys, pheasants (even the odd peacock here abouts) - or around the back streets in our towns - a very long way to go.
