Driverless Cars are being investigated because of concerns over the risks to passengers by the magnetic fields generated by the vehicles.
The United 
Nations has a task force looking at the levels of electromagnetic radiation levels in these new cars.
These new vehicles are filled with technology such as radar, lane sensors, sat-navs and wifi.
High exposure to electromagnetic fields has been linked to a range of health issues and this study is to determine if the current levels pose any threat.
The UN economic commission already publishes regulations for levels of electromagnetic radiation from vehicles and an update can be expected after the current review.
Perhaps we’ll need a lead-lined overcoat for every journey is such a car.
