To be clear, "highway=road" is used when it _isn't_ clear what the <br>
classification should be.<br>

No, it doesn't.<br>

That's good!<br>

Tagging roads that you know well as "highway=road" sounds like a mistake.<br>

<br>
I think there's been a miscommunication here - there is no such <br>
default. It's certainly not your fault - English as used to describe <br>
roads in the UK is the problem, with "unclassified" meaning a particular <br>
explicit classification.<br>
