[flagged]
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"
And just repeating things doesn’t make them different, up to 7.5 tones, it is the same speed and that is plenty enough different weight for stopping distance.
But then again, it is a useless conversation because you have no idea what road safety is about as you seem to focus on absolute numbers and the best way to get absolute 0 is to close all roads and ban driving.
