Amazon and Uber, I have not decided which is the bigger menace to society. What I do know is neither corporation wants to take responsibility, for the actions of their drivers.There is a link within the story,of an earlier article from the same investigators on how Amazon is doing this,

....Amazon ignored or dismissed safety concerns about its delivery network to prioritize speed and explosive growth, according to new documents and interviews with insiders.

As they prepared for last year’s holiday rush, managers at Amazon unveiled a plan to make the company’s sprawling delivery network the safest in the world.

Amazon, which ships millions of packages a day to homes and businesses across America, had seen a string of fatal crashes involving vans making those deliveries over the previous few years. Improving safety, the plan said, was “Amazon’s Greatest Opportunity.”

A key part of the proposal was a five-day course that would put new drivers through on-road assessments overseen by an outside organization with four decades of experience in driver training.

But the defensive-driving course didn’t materialize.

Amid the rush of what would become Amazon’s busiest holiday season ever, the class was vetoed. With more than a billion packages shipping in a span of six weeks, the company needed to put drivers to work almost as soon as they were hired, internal documents show.
