Presently, the clearance parameter of the route style is only respected by
polygons (I think). The "online" DRC isn't (yet) sophisticated enough to
respect anything other than the global DRC requirement.

My suggestion for a work around at the moment is to use a grid setting that
places the traces at the desired spacing.

Having a per-net or a per-netclass DRC, both online and off, is on the todo
list. You're not the only person to desire this feature. I have to put some
infrastructure in place to support it. I've been working on it, but
progress is slow.
