Motorcade always pulls off early. The finishing area (especially on big races) is too crowded already, vehicles can damage the timing mat, etc. This was a combo of stupid fan/leader had a bit of 'runner brain', and insufficiently clear course marshal.
While there are a lot of people working these events....many people, (like hundreds) are there as volunteers. Getting volunteers in general has been getting increasingly difficult the last several years...so while frustrating..not hugely surprising.
