I am addicted to this thing by Dare that’s just gone live:
10 taxis in 5 cities across the UK. Pick two drivers and see if they cover the entire Silverstone race distance first.
You can swap cabbies any time if they are not doing their job.

Mind you I have only clocked up 16 pathetic kilometers so far…
