Proposal

Introduce a tag that allows ways to indicate explicitly whether a 4WD vehicle is required to navigate that way. This would also allow routing engines to take into account such ways, so that non-4WD vehicles aren't routed onto roads they aren't capable of. As many 4WD only roads are in rural or remote areas, if a passenger car gets stuck on such a road, it would be at the least a major inconvenience, and (in Australia at least) potentially fatal.

The addition of the words "(4WD only)" or the simpler and universal "(4WD)" after the road name would make identification of 4WD only roads very straight forward.

Definition of a 4WD

It is worth defining what is meant by 4WD for the purposes of this tag, given the proliferation of passenger vehicles that have 4 powered wheels.

In the context of this tag, a 4WD is taken to mean a vehicle designed for both on road and off road use, generally with:

Examples of 4WD vehicles (these are the Australian names for them at least):

Toyota LandCruiser, Hilux or Tecoma, Nissan Patrol and Navara, Gaz and Kamaz trucks, Land Rovers, Range Rover Discovery, Mitsubishi Pajero, Maruti Gypsy

Examples of "soft roader" 4WD vehicles:

Toyota Rav4 and Kluger, Volvo XC series, Nissan X-Trail, Tata Safari

What's not a 4WD for the purposes of this tag:

Lamborghini Murcielago, Audi A4, Nissan GTR etc. If you look at the vehicle and think "there's no way that car could cross a 1.5 foot deep river", then it probably doesn't count as a 4WD off road vehicle.

Rationale

Currently there are a number of either approved tags or proposed tags that attempt to cover the smoothness, surface or other properties of a way, which in turn implies the potential suitability of the road for different vehicle types.

However, there is no way of currently tagging a way in any obvious, visible or easily understood method that indicates a 4WD vehicle is required. The ability to determine easily whether the road condition is viable for standard cars/truck/buses is not currently available in the map.

While the highway=track and track_type=gradeX tags can be used to determine this, this approach forces all 4WD only roads to be classed as a track irrespective of their actual classification. In Australia, there are a number of major roads which are classed as either primary or secondary that are also 4WD only roads (eg: the Peninsula Developmental Road between Daintree and Weipa in far north Queensland, and the Buntine Highway in Western Australia)
