For some reason I'm not at all surprised to learn that Uber programmed their vehicles to speed. Of course they did. This is literally "move fast and break things" at work.
Studies have shown that the rate of driving accidents is minimized when a vehicle travels at the same speed as other vehicles on the road. This means that in many cases, “speeding” with the flow of traffic provides the safest outcome. Although in the case of this accident, it appears that there was no surrounding traffic.
