ULEVs - Good News/Bad News

This report from Edie trumpets a rise in ULEV registrations in the UK of 1864% over 5 years. All well and good but what really matters is the absolute number of vehicles on the road. That apparently spectacular increase is actually from 2129 to almost 100000. Let's put that into context. There are approximately 35M registered road vehicles in the UK. So that 100000 represents less 0.3% of all road vehicles. We all know that "mighty oaks from little acorns grow" so any increase in ULEV registrations must be welcomed. There is, however, a long way to go.
