The aliens were assholes but they were good at solving problems. One of the first things they did was to improve the timing of traffic lights so the flow of cars was smoother and drivers spent less time at red lights. They claimed that the system was based on detailed census data and records hacked from the dmv. In fact it was a complex mind control device using pheromones and sound waves. Does it matter that they lied? Everyone got to work on time.
