There aren't many rocket designs in use right now that have had more than 100 flights _total_. It's hard to properly evaluate the safety of a system when it only gets tested once a month. As the cost of spaceflight comes down and launch frequency goes up, I suspect we'll start seeing reusable launch systems emerge that have had thousands of launches across dozens of rockets. Once that happens I think spaceflight's safety record will improve significantly.
