The idea is to launch a small drone aircraft when the vehicle leaves its depot. The drone would not have to be very complicated, just a biggish model aircraft with down and forward looking camera and a data link to the vehicle.

The drone is controlled by the driver's mate and is flown some few hundred yards or so ahead of the vehicle so that the operator can warn the driver of hazards ahead rather like the way a rally navigator advises the driver.

Avoiding just one crash would easily pay for the drone and all those model aircraft nerds would make willing fire/ambulance service recruits.

Similar black market versions would be available for bank robbers.

All drones would be fitted with ACARS to prevent nasty mid air accidents with other drones being flown by the TV camera trucks.

(I know someone will recommend air to air armaments)
