The subject of making electric vehicles compulsory in city centres in the UK, and indeed many other areas of the world, is one which keeps popping up time and time again. The Liberal Democrat party in the UK has been pushing for greater adoption of electric vehicles within city centres and, don’t shout this, a ban on diesel and petrol vehicles. This is now something of a hot topic and one which will continue to appear in the political domain as we approach general and local elections.How would you feel about making city centres a no-go area for petrol and diesel vehicles? Is electric vehicle technology of sufficient reliability to support such a dramatic and controversial move?
