Full results of the BMW Group's UK government-supported research into the day to day running of electric cars out on Thursday (4 August) revealed: over 250,000 miles were driven on local roads, the average cost to charge was less than GBP0.02 per mile, the average daily distance driven was 29.7 miles, virtually all recharging was done at home and that "almost all" participants said they'd consider buying an electric car as a result of taking part.
