Personally I don't agree and think your comments are quite unfair. I have no affiliation with Wicklow Co Tourism and in view of your comments had a look through the website, which I found quite informative and interesting. The map link gives clear driving instructions (your original request) from the M50 to the Great Sugar Loaf.

If you feel that strongly about the website perhaps your remarks and any constructive suggestions for improvement should be directed to Wicklow County Tourism and not to this forum.
They've given contact details for specific enquiries, as follows:
