I wonder if we are seeing the "24 hour news effect"? We now get messages alerting us to accidents over a huge geographic area. Years back, we would never hear such things. This amplifies the effect of more accidents.
The "24 hour news effect" is the same thing. For example, everyone thinks children are being snatched up left and right, but if you look at the numbers, this is not the case. It's just- we hear reports from all over now, which makes it seem that way.
