You never stated that there was a massive crowd surrounding Mary and could have easily been hurt too. If you're going to post a story like this, get the facts included so that others aren't unnecessarily worried. No-one needs sensationalist headlines whilst making a mountain out of a molehill. By the way, it's Queen Mary, NOT Maria.
Go to Google and take a look a the rather quick footage. Mary was standing in amongst a huge crowd of people. I'm sure her security would have been present, yet when you look at how crammed in all of these people are, how are they supposed to even see this coming in the first place? It's very easy for many in the public eye to feel safe mingling with the public and this is the risk that they take. It appeared more like a stunt by the driver to garner media attention as he went directly towards Mary. He ploughed through many others before reaching near Mary, so some thought should go towards these people too. Take a peek at the footage and it will be easier to understand.🇦🇺
