The reason that I mentioned not riding near large trucks was because of an incident that happened on 696, down in the lower sections.
I was in the car in the far left lane. A semi was in the far right lane. Only 1 car was near him, in the second to the left lane.
His rig blew a retread. The tire came off the wheel like a donut. It shot across 4 lanes of traffic and smacked into the low divider wall where it left a great big rubber "O" imprint on the wall.
Cars were panic braking all over the place. Had I been on a bike, I probably would have been hit by the breaking cars. The truck just kept on going.
But a bike would never have survived had that rubber donut hit him.
So I do my best not to ride next to trucks.
