While it's not an open-and-shut case of reckless riding, first person accounts on Universal Hub of the crash that killed 24-year-old swim coach Marly Pineda in Brighton make it highly likely. Not for the feint of heart.
I was the 1st car at the red light looking to go straight onto Kelton Street. There were no cars at the red light coming from Kelton but one was driving from a distance. The light turned green, and just like anyone coming up to a green light, the car just proceeded to drive through the intersection as he should. Right when he got to the cross walk a biker (girl, mid-late 20's) FLEW through the intersection with no caution whatsoever and got SMOKED by the car!
I saw it too. Was waiting at the red light on Comm Ave. The driver from Kelton Street didn't have a chance to react. The bicyclist came from nowhere, way too fast down the Comm. Ave hill, and ran the red light. The driver was not going fast, and the driver had the green light.
If these accounts are accurate, the young woman was riding at a good clip, didn't see anyone in a limited field of vision, and went through the intersection, which others describe as among the worst in Boston.
Does it really need to be said? If you're not careful on a bike in traffic you could get killed.
