An Amazon driver nearly clobbered me a few weeks ago. Pulled into my path from the right, never looked up from his phone or navigation device. I noticed him slow-rolling past the point where most drivers stop so I'd already begun coasting and had my hands on the brakes. I caught up with him and fussed a bit but didn't report it since it wasn't deliberate. Just careless. I suppose I didn't want him to lose his job.
But that's only one incident, not a pattern. Most Amazon drivers seem to operate pretty much like USPS, UPS and FedEx drivers.
I'm not seeing many contractors for Amazon in personal cars doing deliveries now, especially with same-day deliveries cancelled for now. No telling whether they're more negligent since their vehicles aren't marked.
