I don't have the data, but my car insurance is considerably lower as a result of modern safety features in my vehicle. My insurer has a large checklist of things which correspond with a discount, such as automatic breaking, cameras, blind spot sensors, lane departure alerts and steering, etc. In total it comes to nearly 15% for my vehicle. I suspect it means these things actually save my insurer money on average.

Which brings me to the point of common sense. Not everyone shares it, or uses it, and so these features are useful. We can talk all day about what people should or could do, but at the end of the day, it just isn't going to happen.
