Are electric cars getting a bad rap in ship fires?

When a fire strikes a car carrier, the first question asked is often whether it was started by an electric vehicle. But while the growth of electric car shipping and the hazards of lithium-ion batteries do require special measures, a growing body of evidence suggests they may not be more dangerous than conventional vehicles. We talk to Andreas Enger of Hoegh Autoliners, and Bingbing Song and Heike Deggim of the International Maritime Organization about the measures under way to make vehicle shipping safer.
