Lipo are they dangerous?

[Yachty]

Has anyone else had any serious incidents with Lipo as I stumbled across the following article. As I race both 4wd offroad battery cars and yachts.

As we know for off road events presently lipo is not allowed which before ordering my Cat SX which I am presently buidling I thought was a pain as Lipo clearly had a competitive advantage so on a world stage this seemed strange. Maybe this is a wise move to not allow Lipo? Any other bad experiences or is this an isolated incident and we shouldn't be worrying? I have mistreaded normal cells all the way through my teenage years without any consequences I am more carefull now is lipo worth the risk? I certainly wouldn't let kids use them.
