A question for the Victorian's I just got an infringement notice from Mr Bracks & co for speeding whilst holidaying in victoria ( I'm not saying wether I was or not ; ) )& while we were traveling we noticed a few lights flash behind us, there were 3 bikes traveling together & reasonably close to each other. Anyhow we all scored an infringement with varying speeds. 81,84 & 88 kmh. my question is if 3 bikes appear in the photo how do they know who was going what speed ?? Has anyone had any prior experience ??
