It came preinstalled on my Archos Cesium 50 Win10 phone.
Seems a pretty long way from Here Maps and Here Drive as a driving assistant IMO. The user interface is poor.
I'm still very confused by the different variants of Here: Here Maps, Here Drive, Here Drive+...
I've tried to install Here Drive+ on the said Archos phone, it did install from the Windows Store but I can't get past the login screen: the keyboard doesn't show up.
Sad because it's a nice app. I use it a lot on my Lumia 535.
