I think that spike is just the two normal days between 22nd's curfew and 25's lockdown

Definitely not normal because you can see the spike in grocery stores. People were stocking up.

Umm, but the activity is still lower than the baseline of normal day.

There is no reason to expect a sudden increase in cases because of those two days in particular

Perhaps because Google services are blocked in China and Android phones there don't have Play Services with Location History? You can't plot data you don't have ;)

There are millions of people in China with always on VPNs, and they still have a non-insubstantial business in the country. The thing is, the geographic data there is protected by law, and they don't want an espionage charge. The same is provably true for a suspicious missing of a few other countries with similar attitudes.

But Google probably doesn't want to rub that fact in China's face and risk a more aggressive crackdown.

I wonder if the graphs are affected by a "starting" bias, meaning is the mobility on the first date, February 17th for the charts I was looking at, used as the measure for seeing the trend on subsequent dates. The issue what if that date was particularly cold or rainy and then as we moved into March the weather got better of course you would see greater mobility movement as compared to a cold February day esp. the category of Parks and recreation

But instead had they used is sliding window for the baseline (i.e. using the average of the mobility for the past 3 years) for any given day then seeing what this year's date is as compared to that we would see (hopefully) a dramatic decline.

Just thinking out loud

Take care and STAY DISTANT

I think that Google and Apple will be extremely helpful in the coming months, at least in the USA, for tracing the spread of COVID-19. Google and Apple know where probably 90+% of adults/teens in the USA are located in real time. If they are able to anonymously tell you that you were in the same building as someone who has tested positive for the virus then you could take extra precautions or further isolate yourself…

Google and Apple are now doing a version of this: https://techcrunch.com/2020/04/10/apple-and-google-are-launc...
