Anyone have any idea what substance was on the road near roberts rd this afternoon? It was barely noticable and I didn't realise there was something wrong with the surface until ABS kicked in and a slight skip of the front wheel sideways as I came to a stop. Didn't look like oil or diesal but the tyre flicked whatever it was onto the exhaust and a white smoke was created. Putting my foot down was really slippery as well. Got out of there OK, and there was a fire engine nearby for what seemed to be an unrelated event. Wondering if anyone knew what it was and a heads up to anyone going through there along the train line.
