In Hungary, almost all of serious accidents are caused by speeding on some level. But you can’t see this in official statistics, because the national statistics office gathers data after one month of the accidents, at which time it usually isn’t decided officially the cause, so it defaults to “speeding is not involved”.

Another interesting info is that almost 100% of fatalities of car passengers are people who don’t use seatbelts. There were years when all of the fatalities were cases just like that.
