Oh okei. You're unsure how it happened. I asked because I was curious about how you came to your statement that the "driver cum father/husband" would have a stupid face, without any solid evidence to back your claims. Well, that's considering the fact that you mentioned "father/husband" and that it felt like you were blaming that dude for wreckless driving instead of the truck/lorry/etc. driver. I would certainly believe that how sad that "stupid faced driver cum father/husband" will feel about this accident. No worries. You needn't justify it to me. I'm just curious, that's all.
Usually, I would always suspect the truck/lorry drivers who are the ones that are wrong because 8 out of 10 really large vehicles like trucks, lorries, busses, etc. that are on the road are wreckless and seriously inconsiderate drivers. They just swerve in and out and drive over their speed limits. I've experienced a few times when I was driving at 100kmh on express ways in the middle lane, over taking cars on the left lane, and there will be express busses or trucks who will high beam me to move over. As far as I know, their max speed limit is only 90kmh. What are they trying to do by driving faster than 100kmh? Exactly what the govt is doing to the citizens. Slowly and surely killing people.
