I personally train handling instead of driving for my small men. I feel it increases driving enough but increases the more important skill (Ha) which factors into the game in more facets. Plus as an added bonus you can single position train it which gives more driving than dual position training driving itself.
I have to agree with this.
However, if you look at Joseph Ka's weights, it seems to suggest that leaving driving at atrocious is the way to go. I'm not convinced that is the case. Probably it is the least important guard skill, but I don't think it is completely unimportant.
