A little while ago, I had a nice little surprise recently while watching Top Gear. They examined what to do if you crashed your car in a body of water. My ears pricked up at the mention of this because I used that exact situation in my first novel, ACCIDENTS WAITING TO HAPPEN. In the opening chapter, the lead character is forced off the road and into a river and he has to work out his escape from a rapidly sinking car.
I was interested to see what they discovered to see if I’d guessed right. Whereas Top Gear has the budget to drop a car in pool with a camera crew, I don’t. For the book, I relied on my engineering background for what would happen. I knew there’d external and internal pressures as a car sank and you’d have to be Arnold Schwarzenegger to force open the doors. I also considered that power windows, etc. wouldn’t work either. My solution for escape was a play off what I was taught in flying school. If you ditch in the sea or something, I was told to open the door before impact, because you won’t be able to open them with the water pressing against them. In the book, my character breaks out through the windows before the car has a chance to submerge. This goes against conventional advice of sticking with the car while it sinks, let the car fill up with water and when the pressure has equalized, let yourself out. If this proved right, there was a rewrite on the books.
Well, my escape theory proved right and conventional advice didn’t work. I was very proud of myself. Yay me!!!
The practice test proved that it took a long time for the pressure to equalize and you would most likely run out of breath before then.
If you’d like to see how it all went, please watch the video clips.
Consider this blog entry a Public Service Announcement. My advice is to have something in the car to break the windows should you ever end up in the water. You want to get out as soon as possible. 🙂
