Does the Extraterrestrial Alliance contribute to snarling traffic? If so, how is that orchestrated?

This, in fact, is done as a routine to the extent they encourage and assist the spirit meddlers. You already know that spirit meddler attachments are a very significant contributor to auto accidents by manipulating their host to distract them from within at key moments where inattention gets them into trouble and then there may be a collision. This is a beautiful way to cause traffic jams and long backups that not only reduce human productivity through lost time at work, and so forth, but also add greatly to daily stress and this takes a toll on the health and well-being over a longer period of time to worsen things and even shorten the lifespan. There can also be an orchestration of events more directly through subliminal programming to cause people to converge on certain areas, and use certain roads simultaneously, and this will inevitably produce a logjam that can tie traffic up for hours. It is one of many ways they darken the human experience and while it may seem petty, the effects are quite real both in terms of lost revenue and the cumulative damage to people with significant suffering following years of extra stress due to this cause.
