Roundabouts

ok - so I am a non technical person and I see alot of smart people belong to this site. So here is my question....

 A developer wants to put a roundabout in the intersection near my house - truth be told it is on my corner. This is a rural township  - should I be concerned?  I know that they are all around the UK and  Europe, but roundabouts   are somewhat of an anomaly in rural Pennsyvania - what do you experts think?
