Looks like Brian was lucky that the cager took off really slowly. If he was in a hurry and floored the throttle it might have been a very sad day.
Wasn't all that slow. One of the things that drew attention to the van as it approached the stop sign was that it was approaching a little faster and braking a little later than most people. Looked like the driver was in a hurry.
This could very easily have turned out differently. Half a second different timing and it may not have been avoidable.
