So I did more digging and found an article from 2012 talking about BMW linking up with it's navigation system to sense when to decouple the trans...looks like it's finally made its way into cars now that Navi is standard:

When set to Eco Pro mode, BMW claims that fuel efficiency can be boosted by as much as 25 percent, and if the driver selects the Foresight Assistant feature, their Bimmer will choose the most efficient driving route and provide tips on maximizing fuel economy through the center-mounted display. Additionally, the system can recognize when coasting would max out the MPGs, decoupling the transmission from the engine at the most opportune times.
