Haha, yes, MUCH less safe. If you google millimorts, you can see how risky various sports, activities are.
However, ultimately, much as most won't admit to it, there is a trade off between safety and utility/enjoyment. I feel sad seeing children in all over wet suits on summer holiday with those kind of Moroccan hats, just in case they get some sun. Or, toddlers wearing crash helmets to toddle, just in case they fall over and hit their heads.
We all die eventually. It is unavoidable. And when you see children scared to indulge in activities we regarded as normal as children, that is the trade off against them being a little safer.
And, yes, this is about this thread. It is MUCH nicer for a child to travel facing forward like a normal human being. I know how happy ours were when they first changed, a few years ago.
