It asks for your location?
I have to admit that the UK's solution does reflect the typical desire of British governments to treat the general population as peasants to be controlled, but to say that the app asks for location is overstating it a bit.
It asks for the first part of your postcode when you install it - so in my case it would know where I normally reside to within around 20 miles (even assuming I gave it the right info) and know nothing about where I actually am or what I am doing.
