I don't know the specifics of this accident but I use this road alot. I think Cross Road is generally OK for cycling but there may be some contributing factors near Highgate:
The sun glare may have been a strong contributing factor when a person got killed cycling through the Anzac Highway/Cross Road intersection about this time two years ago (later the subject of an AC memorial ride).
Considering the high numbers of cyclists using Cross Road to get into the hills I think it would be reasonable to put a strong case to Dpt Inf. and Transport for continuing the bike lanes up to Portrush Road and removing the bottlenecks. The traffic can get pretty heavy and there are often wide trucks, busses, and people towing caravans.
Peter, suggest you start an AC discussion about seeking cycling improvements to Cross Roads and get feedback from other cyclists. They may come up with other cycling hazards. Also, does not hurt to get support for your cause before approaching the authorities.
Three of my cycling friends were killed by negligent drivers. More cycling acquaintances who were hit, injured, maimed or killed on the roads. Includes AC members. I did not personally know anyone who died as the result of road trauma while a car occupant, but obviously happens as reported by media and govt statistics. I have been injured on three occasions by negligent drivers. Despite being an experienced utility cyclist, mixing it with peak hour arterial and CBD traffic since 1984. I identify as a cyclist.
Cycling is hazardous, mainly due to drivers, but could be made safer by better cycling infrastructure, better driver training, and 'hip pocket' education of Strict Liability Legislation. As reported on AC, this month police let a driver off with only a caution, when he/she left the scene after the passenger doored and injured a cyclist. I will keep advocating for improved cycling conditions. Repeated surveys give the main reason for not cycling as 'unsafe'. Improve cycling safety, increase numbers and cycling will become even safer when more people know a cyclist and how to drive near one.
