I could see this having large adverse selection effects. All the "low risk" people buy cheap insurance from Google, and the incumbent insurers are left with a pool of only high-risk customers and have to dramatically increase their rates accordingly.
Even if that works well for 99% of people, it could have seriously negative effects for some. After all, a 99% accurate ML algorithm still leaves 1% of "innocent" customers with no way of getting affordable insurance.
