Actually, Paul asked the same question before.
I'm attaching the part to answer your question.

o	Wipers 
	Wouldn't it make more sense to have one wiper interface instead of two as they both have to do with wiper?
	Why do we have wiper setting and speed?  Their seems to be overlap.  I get that their is a correlation between the two.  Just want to make sure we are being explicit about it.

==> Unlike other attributes, wiper is hard to have a common interface for both ‘get’ and ‘set’. Since ‘once’ and ‘auto’ exist in only setting status. In ‘auto’ setting, wiper speed varies depending on the rain intensity. So, I thought it needs to be separated.

Usually, defrost is supported for Wind Shield, Rear Window and side mirrors.
We can apply zone for it with 'Front', 'Rear', but side mirror is not much matched.
And Side windows usually are only for 'Openness'. So, even though all are 'windows', but the usage is different.

I intended separating airRecirculationg and steeringWheelHeater attributes not associated to zone from HVAC.
Overall, we need to find-tune the granularity of interfaces.
