With the benefit of hindsight, it's always easy to avoid these accidents.
We are watching a DC clip - so we are expecting something to happen
We have a brief explanation "dangerous UPS truck driver" - again, we KNOW something will happen.
in this instance, I have only ever seen UPS using the transit vans - so seeing this big rig was a surprise for me.
When you're at the speed limit, you often don't notice these things until you're committed.
