Source: It isn’t always cars that kill cyclists. It can be a moment’s inattention, an obstacle in the road, a driver passing too close, or a rider exceeding his or her own ability. We may never know why Lihsiang Chang fell while riding her bike last Thursday. All we know is the 54-year old cyclist was riding north in the bike lane on the 11200 block of San Diego’s El Camino Real around 1:45 pm when she somehow lost control of her bike, on what’s described as a steep downhill — even though the road doesn’t look that steep. She suffered a serious head injury and was placed on life support at a La Jolla hospital. Sadly, Chang was taken off life support yesterday and died around 5 pm. No other information is available at this time; this is one instance when knowing if she was wearing a helmet might have mattered.
