Went down Coulter Drive at 9am, just before the lights on William Hovell, and there was a big operation going on. At least three police cars pulling drivers over. At first I thought it was a breath test, but I think they were checking tyres with some sort of calliper arrangement. Hard to be sure because I only had a quick glance as I was waved on. There were about half a dozen driverless cars sitting there on the verge!
Anyone know what was doing?
