Over my head, autocabs wove in and out of the traffic with programmed hyper-efficiency and swooped occasionally to ground level in attempts to stimulate custom. The weather above the traffic flow was on the change, grey cloud cover racing in from the west and occasional spots of rain hitting my cheek when I looked up. I left the cabs alone. Go primitive, Virginia Vidaura would have said. With an AI gunning for you, your only hope is to drop out of the electronic plane. Of course, on a battlefield that's a lot more easily done. Plenty of mud and chaos to hide in. A modern city — unbombed — is a logistical nightmare for this kind of evasion. Every building, every vehicle, every street is jacked into the web, and every transaction you make tags you for the datahounds.
