Personally, I don't think fear of dangerous traffic is a very useful metric for deciding where to live either. Also, if ISIS does successfully conduct an annual terrorist attack on the Brussels Metro then it might be something worth being more afraid of. At this point, treating it as a major factor in deciding where to live is just fear-mongering—especially when I personally think a place having previously suffered a terrorist attack lowers the future risk.
