Sorry but that is technicaly nonsense. The first problem is that nobody has any hard data for EV used in rallying, therefore nobody can compare the probability.

The second thing with battery fires is that they carry their own oxygen and therefore don't need air to burn, hence why it is impossible to extinguish the fire before it burns all. In other words if the car catches fire in a forest it will burn for an hour or so not for five minutes as with the combustion-engine powered car and the fire brigade can basically only localize the scene and wait - that is extremely hazardeous in windy and dry conditions and you need tons and tons of water for that.

The third and not smaller problem is that the fire is very very difficult to anticipate because the fire can start basically anytime after a battery-damaging incident over a very long period of time. The first issue here is that it's often impossible to recognize what is "battery-damaging" incident. It can be a hit on the vehicle floor which causes no visible structural damage. That is something which happens pretty often in rallying. How to prevent that? Will the batteries go to a quarantine after every service stop and stay there for couple of weeks? IMHO that is hardly possible.

There are also numerous incidents known where the batteries started fire repeatedly again and again, especially if they were well-charged in time of the incident.


He also completely omits the hazards connected with the high voltage and accessability of the vehicle for untrained personel in case of incidents on rally roads (fans, common stage marshals etc.). These people will reach the vehicles before any specialist can reach the spot because it's not a circuit closed from public.


The risks may be "low" but first someone needs to hard define what "low" means. The probability of a spectator being involved in an accident is also low, yet we do everything we can to prevent it.
i really can't understand how you know this better than who built the car!
