It's still in regular use around town, still does around 140mpg, and I have used (and wouldn't hesitate to use) it for long journeys.
When the fuel gets low, it takes a couple of minutes to fill up, not several hours to recharge.
The 'fuel tank' doesn't need replacing every several years when it loses its ability to charge.
All of which must be food for thought..!
I'd even happily ride it to the NEC for the bike show, just to get back on topic
