Did anyone see if the lorry was indicating left? Also, did anyone see if the cyclist was on the inside of the lorry? The 'infrastructure' there encourages cyclists to go on the inside of vehicles. Up until the introduction of Bikeability cyclists were generally taught to stay on the left and always use bike lanes - an attitude that many cyclists and drivers still retain. People often have a go a cyclists for not using bike lanes, even though the legacy ones are often pretty dangerous, so it's not beyond reason to see why many cyclists go on the inside of vehicles.
