Thank you Lord Duncan
"He said once electric vehicles become mainstream, people will want to use their smart meters to find out the cheapest times to charge their cars."
Once again the blinkered capitalist ignores the fact that most people can't, and probably never will be able to, afford electric vehicles plus the means to charge them at home. The shortage of "affordable" homes with drives or garages and the drastic shortage of homes with any dedicated parking space at all will not go away - it can only get worse.
