A number of studies have been carried out into electromagnetic radiation from electric vehicles and have found that passengers aren't exposed to dangerous levels of radiation. One study, carried out by SINTEF (an independent research organisation headquartered in Trondheim, Norway) found that exposure was less than 20 percent of the limit recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

In terms of electric cars in traffic jams – if anything, they're better than petrol or diesel models. If you're stuck for six hours on the motorway with the engine running, what's stopping you from running out of fuel? An electric vehicle uses very little power when it's stopped. It also has lots of warnings when you're close to running out of electricity – and will usually have a 'tortoise' mode letting you limp to the hard shoulder. You'd have to be quite committed (or daft...) to run out of power on the motorway.
