In Navevo's case the data will be used to flash a warning symbol on its sat-nav maps when a driver approaches a "warning zone" with a 50m (164ft) radius circle drawn around the area.
It currently doesn't believe the cause was its ( previously recalled) Lithium-ion battery, exhaust routing or electrical components, having learned that the ignition zone was outside the engine compartment, in front of the driver's side front tire.
