My utility gives me half-rate electricity if I charge after midnight ($0.11/kwh vs $0.23/kwh) - people will line up and wait for 20 minutes or drive across town

My utility gives me half-rate electricity if I charge after midnight ($0.11/kwh vs $0.23/kwh) - people will line up and wait for 20 minutes or drive across town to buy gas that's $0.03/gallon cheaper, I think they'll figure out how to set the 'delay charging' option on their car if it gives them the equivalent of half-off gas prices.
