Is the slow-down really that bad?  I have a fairly complicated map which 
  uses TYP files to define a lot of additional polygons and overlays and 
my GPS can update the screen no problem even when travelling in a car at 
70 mph.  For pedestrians or cyclists there would be no problem 
whatsoever.  Perhaps older GPS units have much slower CPUs?

I'm in two minds about the traffic calming patch.  It's of no particular 
use for pedestrians, and will just clog up the map.  And whilst it would 
be useful for road users, so would traffic signals, which aren't 
currently showing up in the default style (or at least, they weren't 
last time I checked).

This is why I think we should have a default style repository - one for 
cyclists, one for pedestrians and one for motorists.

Then an additional repository where anyone can contribute their own 
styles/TYP files, so that the community can learn what tricks, display 
customisations etc are possible.
