Well that depends have you asked a 'lectric company for a a supply recently? It doesn't come cheap, a company I know has just paid over =A35k for one and they dug the 200m trench and laid the duct not the power company.
A small boat type turbine will generate enough to keep a battery topped up at the envisaged useage. Always asuming you are not in a sheltered position...

Perhaps it will teach him to be able to see the road ahead clearly at all times. By keeping his distance, or whatever. If he didn't see a chicane or speed hump, I doubt he'd see a kiddy at the side of the road.
And also the car he was following must have seen the chicane and driven round it. If he didn't see this he shouldn't have been driving.
