Radeng - supports your post as to interference of computer systems.
Long distance lorry driver Peter Orr told the Eye [Private Eye, 7 July 2006, ‘Road Rage’) how his modern truck, equipped with a high-tech engine control unit (ECU) suffered brief loss of control as it passed through areas of interference: ‘Interference from powerful radio signals is knocking out the brakes and gearbox in my truck and others. In the last two years there’s been a massive boost in radio aerial power. We’ve had serious issues with our trucks. It affects the gearbox and braking of 44 ton trucks, but it doesn’t leave a memory in the computer system. It just says: There’s a fault on your ECU’.’
He said the problem was acute in France but also occurred in Britain. including at a motorway service station, where there were communication masts either side of the road. He had reported the issue to the Vehicle and Operator Services Agency, the government body overseeing vehicle safety, in February 2005, but feels he was brushed off.
