Use your common sense, please!
Lots of talk here about fleeting contacts not being picked up, or resulting in a later notification to quarantine when it was not necessary (distance, passing cyclist in car etc).
It's likely that the time spent close, plus the amount of times spent close, would be taken account of. E.g. multiple contacts or prolonged contact may be needed to trigger an alert to quarantine as single, fleeting contacts may be deemed to be of less risk.
Also, many people saying it won't pick up this or that so won't work. It doesn't have to be anywhere near perfect, it just has to be good enough, to work well enough, at reducing infections.
Obviously it was complete crap so the above is moot.
