Westminster App to tell motorists where there is an available parking space

We nearly said the App would tell you where there is a free space, but "free" is not the word to use in conjunction with Westminster, where parking currently costs up to £4.40 per hour.

The idea is that sensors in the road will alert drivers to unoccupied parking bays. That means less aimless driving around and potentially less congestion, as up to 30% of urban traffic is made up of people trying to park, which seems ironic – some traffic jams are apparently caused by people who are trying to stop driving.
