I get route suggestions all the time, so you're not alone there.
Something that might be worth a try to fix the problem of Maps suggesting to take you home (to the wrong address)
Go to Settings > Privacy > Location Services > System Services (scroll to the bottom)> Significant Locations. It will need your touch ID to view Significant Locations.
From there you could either scroll to the bottom and clear all history (including any favorites), or you can select the locations of your home, slide to the left and tap delete.
From the Settings > Privacy > Location Services > System Services you could also turn off Location based alerts and suggestions.
You could also turn off Significant Locations so it will stop tracking your habitual patterns.
Edit: Additional info...
If you have iCloud Maps turned on, deleting the significant location history really won't work, because iCloud will repopulate the history.
So you would need to turn off iCloud Maps to prevent iCloud from synchronizing map data. Go to Settings-> [username]Apple ID -> iCloud -> Turn off Maps.
I imagine after a while you would be able to turn it back on, just give it time for the iCloud data to be wiped out.
