Considering the time, momey and manpower required to fit the flywheels, they might as well wait until the need for cascades is due with the GKN earmarked services being replaced with Streetdecks. Given the recent service changes as well as other services due for an upgrade, I think it will happen within the next 12-18 months.
Given that the two vehicles fitted with the GKN Flywheels have now had them removed, I think that suggests what the success of the flywheel was like (up here, at least!)
I cannot imagine a report being published, though.
