@Gargron how could you, delete such a masterpiece of a toot?!

The street that my mum lives in is a one-way street, but wasn't marked as such on #Google Maps. This caused many drivers to drive the wrong way. I have tried to edit it on Google Maps (there is such functionality), but to no avail. No matter how often I submitted a change (with photos of street signs!), Google said "Sorry, we could not verify it".

Solution: Edit the street on #OpenStreetMap! A few months after I did this, Google seems to have stolen the data, as it regularly does, and now the street is correct in both datasets!
