added note about parking lots/private drives to stop points section
Note: if you have aerial images turned off, such that the background screen is white, you will not be able to see the dashed line. Because it's white.
*Waze is working on a way to specify a stop point on a street other than the named segment the address is attached to. This is important for any mall location, unnamed long private streets/drives with multiple addresses, or businesses which have an entrance from a parking lot off the named street. At this time, there is no way to guide the drivers within a parking lot.
