School Bus: You saw the bus rolling and had enough time and distance to brake hard and turn right to avoid the bus. It's obvious there was going to be a squeeze. Riding like that will get you killed some day. See the squeeze before it happens and avoid it. A collision with a bike vs Car/Truck/Bus- you lose, regardless of whose fault it was. You're sticking your head into the lion's mouth and waiting to blame him when he bites you.
Wanksters: Nothing you could have done about that.
