Bluetooth contact tracing
How many false positives are these devices going to create? Bluetooth on a phone is approx 30 foot distance with no way of knowing how close another device is. If I'm sitting in my car outside the house, about 25-30 feet away my phone picks up my smartwatch if it's on my desk upstairs and my Shield, also upstairs. That's a hell of a lot further than the 2 meter distancing rule in the UK and means if you live on a busy street your device would be paring with people going past outside your house all day that you never had any contact with. Maybe I'm missing something but that's going to lead to a lot of people being stuck indoors for 14 days for no reason.
