Here is a place to start for reliable information on this topic that is neither alarmist nor dismissive about the risks: https://www.evfiresafe.com/
Re the fire at the airport, the details that are often left out are that the vehicle’s battery had been seriously damaged by some sort of collision. It had been removed from the car but then left out in the weather on the ground next to the car and then other cars were parked in all around it in a hire car depot. For a week that included some severe weather it was left like that. Eventually, presumably with rain water inside the breached casing, it caught fire and then burned the cars packed in around it. It should never have been left like that by people who knew it was severely damaged.
There have been 6 fires involving electric cars in Australia. Another was also caused when an EV following a truck was unable to avoid running over something from the load of the truck that fell off. The EV provided warning to the driver. The driver and passenger were able to safely pull over and get out of the car before anything happened.
Three EVs have burned because they were inside buildings that burned for reasons that had nothing to do with the EV. ie not the fault of the EV.
One EV was deliberately burned. ie arson.
Surveys in the US and Europe found EVs 20x, 80x or just over 100x less frequently catching fire than ICE cars. However, when they do catch fire, the fire behaviour is different from a petrol car fire, which requires a different response. Interestingly, in the US survey, hybrids were more likely to catch fire than either pure ICE or pure EV.
