Depends how you count. Being is 5x less accidents might be unreasonably hard. But causing 5x less accidents seems reasonable, especially since most humans are that safe. I don't have the stats, but I believe the worst 20% of drivers cause a large fraction of the accidents. That 20% often includes the uninsured, the unlicensed, the drunk, high, emotionally distressed, and the physically compromised (senile, low blood sugar, tired, etc)
