A classic case of target fixation. The bike (motorcycle) was barely leaned over and the rider could have easily avoided the bicyclists. Instead he panicked and kept looking at the bicyclists. Unfortunately for him and them, you go where you look.
Shelly, you might want to consider ear buds. At work in cubicles, I used PK2's for music. When playing, I couldn't hear outside noise and nobody else could hear my music. When I needed to converse, all I had to do was pause the music.
