Well I got to dissagree with you there lads! I can see where you are coming from and in some cases Id agree but to simply write off all tuners that setup using Rolling Roads is a little to much of a sweeping statement for my liking.
I have seen a number of cars setup/mapped on the road detting there nuts off when being run up on the Rolling Road, then again we are fortunate in that we have 1 of the best rolling roads in the country.
I wouldnt dismiss on the road method of mapping/tuning. There are good and bad in all walks of life!!
With an experienced Mapper/tuner and propper rolling road setup there is no reason why rolling roads should be avoided!
