There is a brand new housing estate on the site of the local hospital. This has an extraordinary number of electric cars. Is it because:
a) These houses have drives, and so electric or potential electric car owners will buy one in preference to a more traditional Bournville house?
b) People who buy new houses are less tied to tradition and therefore more likely to accept electric vehicles as the future?
c) People in new housing estates are all new to the area, and therefore more likely to follow herd instinct, and it took just one person to get an electric car for lots to follow?
d) People who have the money to buy a new house also have the money to buy a new car. And just taking a cross-section of the UK new car sales, a greater proportion of those new cars are electric?
