This "it's unsafe" argument always comes from people in need of an excuse for not biking, and because they don't, they have no idea what they are talking about. Of course this argument goes well with most people, because most people are exactly like that: In need of an excuse for not biking. And of course it's always possible to come up with a single tragic example to "proof" that claim. And if none is available it's easy to make one up.
And no, hatred and a comment written in a minute are not superior to academic research based on extensive statistics.
