[Talk-GB] Dual carridgeways

[Alexander Wright]

I've noticed that, in towns especially, you can get two lanes with a divider 
between them, technically a dual carridge way, that don't look good when 
rendered.

Most especially when trunk roads go through towns. The larger size, when 
rendered, of trunk roads means that labels tend to get overwritten by the 
other carridgeway.

Would it be better to map such roads as a single way with a tag "carridges=2" 
and have the renderer do something better?
