Liam,

The Round Abouts are actually easier to flag than a random road closure. 
The Round Abouts are already categorized in the map database just like 
motor ways and residential streets have their own classification. We 
therefore could add the Round About as an illegal option like motor ways 
for the pedestrian route calculations.

Flagging road closures is more difficult because we have to link two 
databases, the maps and the POIs.

There are a rapidly growing number of round abouts in the U.S. as well and 
it would be useful to skip them.
