Are electric vehicles (EVs) unsafe?

News flash people: all cars are unsafe — driving/riding in a motor vehicle is the most dangerous thing most people do on a regular basis. Very few people reading this have not either been in a motor accident where they were injured, or know someone who has (broken bones, bruises from seat belt in my case).

Do electric cars represent a fire risk?

News flash: all cars represent a fire risk. You can't put 10 gallons of petrol (gasoline) in a vehicle without creating a fire risk.

Do EVs represent a larger fire risk than internal combustion engine (ICE) cars?

News flash: ICE cars catch fire regularly. Over 500 per day on average in USA alone in 2011.

187,000 ICE vehicle fires in the United States in that year represent one fire for every 1,738 ICE. With almost 20,000 Teslas on the road, this fire makes one out of almost 20,000 in the past 12 months. If we include other brands of EV, the stats look even better.

Based on the record to-date, I'll take the electric.

Why don't we hear about all those ICE vehicle fires? Because they are so common. They're not worth reporting. On the other hand, one electric vehicle fire & the news media is abuzz.

Some have expressed concern that the fire wasn't extinguished by water. Hint: don't try water on a petrol or diesel fire either.
