Unfortunately, at least in the UK there seem to be many parents/carers who can't be bothered to strap babies or young children in car seats. I have seen it time and again, at roundabouts, waiting in queues or on the motorway kids roaming around the back seat. Then there are those who for whatever reason use the wrong size seat, or fail to strap a child in tightly.
All this things will likely result in death or serious injury to a small child.
Perhaps they think it will never happen to them. Perhaps because they grew up without seat belts in cars they don't see the point.
Are we going to start prosecuting these people as well? or just the ones who have the accident and kill their child. I am sure the mother will be going through hell, traveller or not.
People still act irresponsibly around their children, dangerous dogs, smoking, not having smoke alarms, really early weaning, poor car safety, hot drinks or boiling kettles/pans in the reach of children. Where do we draw the line?
