We're not talking about driving risk per km, that's not what laws are here tp prevent. They're here to reduce the number of accidents, injuries, fatalities...

And you're the one who brought "anglosphere" into the mix. And specifically in the UK, there seems to also be a lower speed limit for trucks: https://www.gov.uk/speed-limits

You're the one rambling off topic. You're the one calling people names. You're the one everyone is flagging. Log off and take a look in the mirror, you might find that I'm not the one "completely disconnected"
