There is nothing that indicates anything other than an accident.

Every time you make a car journey already, you'll be on CCTV somewhere. The difference is that, in future, the car's index plates will be read as well.

The fire is contained. Yes, it's big and it's going to burn for some time. But it is under control.

All indications at this stage are that this was an accident. However, clearly we will keep an open mind, as with all investigations, until we can confirm that for certain.

In simple terms criminals use vehicles. If you want to commit a crime, you're going to use a vehicle. There is nothing secretive about it and we don't want it to be secret, because we want people to feel safer, to see that they are protected.

We're designing for North America, but we have some strategic interest outside. If it's deployed internationally, it will have to be in licensed bands. A lot of developing countries would be easier for 'greenfield' development.
