Focus on preventing accidents...
The cab was mounted to the chassis with spiral suspension, creating a much softer environment for the driver, thereby eliminating much of the back pains and other health risks which had up to then been harmful for driver health in the long run. The ergonomics were also improved by the possibility of adjusting the steering wheel according to the driver's personal taste. In contrast to many other previous trucks, the new F trucks had very large windows which meant improved vision, adding to the 'active safety' (i.e. reducing the risks of an accident occurring).
Since these trucks were used to a large extent for long-distance transport a special luggage compartment was included, which was accessible from an exterior door (locked from the inside to reduce the risk of burglary).
...and reducing injuries
Integrated air conditioning was a novelty in Europe (previous air-conditioning was often an accessory blowing cold air only through a single outlet, creating a strong flow of air towards restricted parts of the driver's body, often harmful for the health instead of protecting it). Passive safety was improved through padding in the cab and the lack of sharp parts in the cab, reducing the risk of injury if an accident should occur. The cab was, of course, tested according to the Swedish cab test regulations, the most demanding in the world.
A light safety cab
Despite the sophisticated cab, careful design contributed to a fairly modest cab weight, but it would have been difficult, at a time before computer-aided-design was generally available, to make a safety cab like this as light as a 'normal' (not safety-oriented) cab.
The original version of the F10/F12 featured a flat roof, which is easily identified. A Globetrotter version would not be offered until 1979.
