The Floodwater Fallacy: What We Get Wrong About Cars in Water

Floods are among the most terrifying events that can befall us, and when it comes to water-logged vehicles, our instincts often get the better of us. But do we really know what happens when a car is submerged? Popular culture has been perpetuating a myth about cars in floodwaters.

Even partial submersion – just 15-20 centimeters of water – can render a car uncontrollable and deadly. Dr. Amy Peden, a drowning prevention researcher at UNSW, warns that many people underestimate the risks of driving through floodwaters. “At least half the drowning deaths in floods are vehicle-related,” she says. This is not just about being swept away by strong currents; it’s also about losing control and succumbing to hypothermia.

The misconception is that a car needs to be fully submerged before you’re in danger. Dr. Peden notes, “Moving water is conceptually hard to comprehend.” We tend to think we can gauge water depth and velocity, but in reality, it’s a gamble. When the water reaches just below the windows, panic sets in.

Experts like Dr. Peden advise getting out of floodwaters as fast as possible if you find yourself driving through them. Don’t try to ride it out or wait for help; this only increases your chances of drowning. Instead, look for a safe exit point and break the glass if necessary. Electric windows won’t cut it when water reaches the switches, so having a glass breaker in your car is essential.

Despite warnings from experts, we still can’t seem to shake off the idea that our cars are impervious to floodwaters. Commercials and movies perpetuate this myth, making us feel invincible behind the wheel. And when disaster strikes, we’re caught off guard – literally.

This isn’t just about car owners; it’s also about how we perceive risk in general. Climate change is increasing the frequency of extreme weather events, including floods. As Dr. Peden notes, “Fatal floods are on the rise due to climate change.” It’s time for us to rethink our assumptions and become more aware of the dangers that lurk beneath the surface – literally.

To stay safe when driving through flood-prone areas, it’s essential to have a plan in place. Know your route, know your car’s limitations, and don’t get caught up in the illusion that you’re invincible behind the wheel. If you do find yourself stranded, remember: break the glass, escape quickly, and stay safe.

As we face an increasingly uncertain world, it’s time to separate fact from fiction when it comes to floodwaters and our cars. We owe it to ourselves – and those who may one day be affected by a similar scenario – to get the story straight. The next time you’re driving through a flooded area, remember: don’t believe what you see on TV.
