Are you sure you have the speed correct?
The approximate top speed of a swift is 170km/h. I find it very hard to believe that the car managed to speed up further to overtake, and subsequently crash without any injury to the occupants.
I would be very suprised if Amazon didn't have a very sophisticated address normalisation process (in Australia, there are several pieces of software that can process generic user provided addresses, and return a specific delivery ID ["DPID"] that ties to an explicit delivery location).
That seem's to be the desirable outcome, if the trade-off for perceived speed is a larger memory footprint. Users directly feel the speed, but are less likely to be affected by a larger memory footprint.
At least when running on Internode hardware, the traffic only runs on Telstra copper; once terminated at the exchange (on Agile/Internode DSLAM), it pushes out into Internode's backhaul/network. (It's a moot point if the backhaul is Telstra owned I guess, or significant parts of the private network is leased from Telstra...)
What? I don't think I've met anyone, ever, whom holds such an opinion. (And I grew up in south west Sydney).
