Unfortunately the people who appear to have money and those you would think are educated, from my observations also ignore seatbelts for children.
My daughter attends a non government school and daily I see teachers nurses and business owners bundle their children into their cars without seat belts and often standing up on the front seats.
One would think that nurses, who must see the injuries caused by motor vehicle accidents would have more sense, but then I see them riding motor cycles without helmets.
Perhaps as you say they are arrogant, I put it down to stupidity or something I don’t understand about the culture.
