Shock absorbers—many of which contain pressurized nitrogen gas as well as hydraulic fluid—can violently detonate when they reach critically hot temperatures, sending shards of shrapnel in all directions. Similar dangers are presented by shocks built into some vehicle bumpers. Tires can also "explode" and send chunks of burning rubber flying.
Electric Vehicles
Roughly 1% of all vehicles on American roadways are electric, and the belief that they tend to catch on fire more easily than a gas-powered car is mostly myth, but fires in "environmentally friendly" cars do happen, and when they do, they're not particularly friendly.
First and foremost, lithium-ion battery fires in electric cars are significantly harder to put out than gas fires. In fact, EV batteries can burn for hours and even suddenly reignite after being extinguished. In addition, EV fires are typically too hot and too tenacious to be put under control with the typical ABC type extinguisher in the trunk of a squad car.
Further, the National Transportation Safety Board
said in a 2020 report
that "fires in electric vehicles powered by high-voltage lithium-ion batteries pose the risk of electric shock to emergency responders from exposure to the high-voltage components of a damaged lithium-ion battery."
