Are you sure about those numbers? 450 MB/s * 1800 seconds = 810 GB. But the fastest WiFi, 802.11ac, tops out at 433 Mbps.
Even at 433 Mbps * 1800 seconds / 8 b/B, that is 97GB. That seems like a big number for firmware; even if maps/games/etc. are included.
Perhaps the Tesla download thing is quoting the peak number not the continuous number? i.e. mine varies between 1.3 MB/s and 1.5 MB/s; but watching my router I can see that things are happening in spurts. My crummy internet doesn't support a continuous 1.3 MB/s.
Thanks,
Scott
