Rain sensor sensitivity

[phuksi]

The automatic wiper rain senror... It says in the manual that the sensitivity can be adjusted by the dial. Should that actually do something? I would imagine if you adjust it to less sensitive the glass would get more wet before it wipes. If you adjust it to more sensitive it would try to keep the glass cleaner.

No matter what setting I use, it keeps wiping exactly the same. To me the rain seemed rather 'constant' and was quite light. And the wipers wiped almost dry glass way too often.

Any experiences?
