Bro, that country is very, very strict of how people can have entertainment, and as well it's a common misunderstanding that all Saudis are rich, but if you just look at the infrastructure you can tell that clearly all of them aren't. Also there isn't a track in Saudi to my knowledge, and these people use rental cars, so it doesn't cost them anything to fix the damages that happen to these cars (I know, what asses), but whatever it's their own country and own culture so I don't really care about them. If they are having fun, let them do so. Also, their ways of entertainment (like this) have fortunately not entirely entered my country, UAE. Sorry if I kinda sounded mean or whatever. Just saying my opinions.
