Three teenagers were killed when their car skidded off the road in southern France, went through a wall and crashed upside down in a private pool, trapping them inside.
The vehicle was a similar size to the pool and the teenagers - aged 14, 15 and 19 - were unable to open the doors and drowned.
Definitely do this! I have bought these for myself and all of my family members thanks to the Mythbusters car submerging episode and news stories like these.
But also, be aware that they may not work at all on modern cars as many have switched to laminated glass for the side windows. Even Adam Savage has spoken about how this invalidates his recommendations and makes cars less safe in certain circumstances.

Recently saw this on Lemmy, too. https://lemmy.blahaj.zone/post/35078257
This is a result of Federal Motor Vehicle Safety Standard (FMVSS) No. 226, “Ejection Mitigation” in the US. It doesn’t explicitly require laminated glass, but the requirements it imposes leave basically no alternative.
