Any 'default' assumption of any user of the data would give a value between
1 and 2 anyway.
As you can see, an assumption of 2 may be the better one here - if you take
passenger cars into account.
As you can see, an assumption of 1 would be the better one here - if you
take lorries into account.

Independently of 1, 1.5 or 2 any router would consider this road with
nearly the same value for the traffic considerations.
Any renderer has a better info with width.

What info do you think has lanes=1.5 then?
What do you think a user can derive from this info?





Looks as if 2 cars can pass each other without big problems.

At least no problems regarding traffic time or the mere usage to reach the
point you want.

But look at the pole right behind - I think they won't try to pass
everywhere without advanced caution.
