I cycled up to St Andrew Sq yesterday to see the thing that whirls people around. (It wasn't working)
Leaving St Andrew Sq via St Andrew Street, I carefully crossed the tramlines - or, so I thought, because my back wheel got stuck between them.
Fortunately, there was no traffic behind me (I have no idea what the traffic rules are around there at the moment) so I had time to dismount and pull my bike out.
But the lesson was clear: the tramlines are a perfect fit for my tyres.
And that might not be a problem on a road with no traffic, but it could be a fatal problem if I was cycling along the tram route during rush hour.
