According to Rubalcava the reaction to the first car bombing using an AV is going to be massive, and it's going to be stupid. There will be calls for the government to issue a stop to all AV operations, much in the same way that the FAA made the unprecedented order to ground 4,000-plus planes across the nation after 9/11. "But unlike 9/11, which involved a decades-old transportation infrastructure, the first AV bombing will use an infrastructure in its infancy, one that will be much easier to shut down" says Rubalcava. "That shutdown could stretch from temporary to quasi-permanent with ease, as security professionals grapple with the technical challenge of distinguishing between safe, legitimate payloads and payloads that are intended to harm." (And don't forget The Dead Pool.)
I have been looking at pre-paid plans from Verizon(only 700 LTE band for their pre-paid hotspot), AT&T, T-Mobile etc. perhaps to put in a MiFi hotspot or buy a hotspot from a provider, but have no idea which one to use, their reputation, real life coverage etc. It is clear that all data plans in the USA are really expensive, I get 100GB monthly traffic with my Scandinavian provider for the same price as 6-8 GB monthly in the US, which I guess could be a problem with our Apple phones as they do not recognize a metered WiFi hotspot. But that is another issue. I travel all over but most of the time outside the big cities -- and my experience from roaming with my own phone and the cheap local phone so far tells me that coverage fluctuates wildly depending on the operator.
