Thanks Li, I have not put that proposal up yet, waiting on a response to a related matter. Soon.
And when I do, I'll not be wanting just your vote, it will be your input I will really need ! Maybe I should put a draft up on my personal page while we wait ?

Since my company focuses on 4WD maps and navigation, we will certainly take full advantage of this. BTW, do you have the link to the proposal page? Will go and cast a vote. Li.

The real issue is how important the data is. As I have mentioned, I am concerned that maps are being rendered that ignore this data. Routing engines are potentially sending people down roads that they, and their vehicles are ill suited to. Bad things will definitely happen. The routing people are saying "but these tags don't even show on the OSM maps, why should we worry ?". And as to subjective, while there will always be borderline cases, I don't think it would be too hard to divide tracks up into - * 4x4 recommended - you will might be OK in a conventional car or (better still) an SUV but you have been warned. * 4x4 required - you really need a stock 4x4, a real one with (eg) low ratio. * 4x4 extreme - this is for the death or glory boys, they need experience and modified vehicles. This is a recent addition ! I am pretty sure that if you and I spent a couple of weeks having some driving fun, we'd agree on the vast majority of the tracks we graded.

By adding a 4x4 recommended tag will add to the complexity because it's kind of subjective as to which roads/tracks are traversable in a 2WD vehicle, therefor adding another option for this key will further complicate the issue.
