Motorcyclists need to have their heads on a swivel at all times. The situation in this video is extremely common and I have encountered it once or twice personally. The driver of the black car admitted he saw the bike but misjudged its speed. He then panicked and stopped right in the middle of the intersection.
It is hard to tell if the rider was going too fast for this section of road or not. The damp ground and parked cars blocking my view would have been an indicator to me that I needed to be extra cautious through there, but video does a bad job of giving a true sense of speed. If it was too fast, it wasn’t by much.
Regardless, when the driver cuts off the biker, the biker grabs a handful of brake and ends up sliding to the ground and into the car.
In this situation, once he started to pull out, the car couldn’t win. If he had continued on his way, the bike may have been able to slow down enough to pass behind, but by stopping, he tried to give the bike an out on the right side.
The biker didn’t have enough time to determine what the car was going to do and instead of going around, stared down the target and ended up smacking into it.
Lessons to be learned? Be extra cautious on a bike if you cannot see cross traffic and look twice if you are a car blindly pulling onto a street. And for both bikers and drivers, try to be as predictable as possible on the road to give everyone else a chance to avoid your mistakes.
