Ask HN: Could Google create a Covid-19 risk score for locations?

[cad1]

When searching for a business on Google, the results will usually include how busy the location is historically and currently. It will also include the average amount of time a person spends at the location. I assume this data is collected from mobile devices somehow.

My question is, couldn't Google take the number of unique visitors and the average amount of time each spends at a location (maybe even the local infection rate) and calculate a risk score that you could view before visiting the location?

I can see why Google would not want to label customers as high risk, but I think this information would be helpful for the public.

That's brilliant but very tough to implement from legal perspective.
