Yes, but that overlooks that despite needing the benefits of Gridguide, the VIP or HTT also needs to have wireless turned off for maximum security. You can install manual override and gridguide override, but that doesn't remove the fundamental problem that as long as one has wireless turned on there's a non-zero chance the vehicle can bricked before you can do anything. Yes, you can put a top notch decker in the vehicle. That'll protect against any script kiddies, and it'll probably protect against any shadowrunners..........but at a certain point, "probably" isn't enough. And besides all that, we all know that the mantra of the super-rich is "rules for thee, but not for me". If I've got enough money, then I don't care that Gridguide only works when wireless is turned on; I want it to work when wireless is turned off, and someone is going to make it that way!
What I'm getting at is that I believe that at the highest level of Gridguide subscription, a secret level most people don't even know about, Gridguide will give you VIP treatment while you have wireless turned off; what I'm asking is how this might be achieved.
My preliminary thoughts on the matter are that perhaps such drives cannot be done spontaneously (by which I mean, there must be some warning to Gridguide beforehand, more than 5 minutes but no more 24 hours) and also that at least one accompanying vehicle must be connected to Gridguide....that there will be at least one accompanying vehicle is a given. After all, we are talking about a level of security where there is going to be a convoy rather than a single vehicle.
