My street has 3 speed cameras according to TomTom.
I put 1 of them there. The number changes from 1-5 periodically....
No pavement on my side of the street, difficult to get a pushchair out when people are doing 60 in a 30 - though 'tis a leafy 'burb - but people still live here!
Swings and roundabouts.
Google could have their mapping people even volunteering to spend 15 minutes a day looking at alterations before changing - or a million and one other solutions, including only certain Google serviced customers doing it.... seems fishy, as though perhaps Google simply want to fully own the data set (?)
