Flash flooding can be very scary. This is dash camera footage of a driver getting caught up by flash flooding.

This is a view from my D-TEG dashcam. I approached a flooded road and made a quick U-turn rather than driving into the water. This was a naturally smart move. Unfortunately my turn resulted in me plunging off a hidden embankment and splashing nose-first right into a swollen creek where I sunk straight to the bottom, I traveled several hundred feet underwater with the car quickly filling up.
At one point I was completely surrounded by water and just holding my breath in the darkness. Somehow the driver-side and passenger-side windows broke and I was flushed from the vehicle. I surfaced after a bit and found myself racing down the creek. A cop called out to me and I was able to swim to him and his life-saving grab.
