<br>
I'm finding a high rate of false positives with the "Invalid<br>
Mini-Rounadbout" challenge - they are mostly flagging up real<br>
mini-roundabouts. I'd be interested to know both what is causing them<br>
to be flagged, but also whether it's a regional problem with the high<br>
rate of false positives (I'm looking in London).<br>
<br>
Thanks,<br>
Andy<br>
