Organic SERPs showing Breadcrumbs

Looks like Google is trying out some new ways of displaying SERP URLs.  In this image (taken by @robhammond), Google is sharing the location of a results page within a site by including the page's breadcrumb string instead of just using the first 51 URL characters.




The Renault UK results page (#7) has matching breadcrumbs on the destination page:



Today, a search for mobility provides the same results with "normal" URLs:

So what does this mean?  Should we all style out our sites with Hansel and Gretel in mind?  Keeping Google's usability priorities in mind, I think bread crumbs should be a mainstay in any site anyways.  Also, I do believe this is a feasible full time change we may see some time in the future. 

Displaying breadcrumbs in SERPs clearly maps out for searchers what section of the site their query result is located within; this will enable searchers to better read those URLs and have a clearer idea of whether or not that result is appropriate for their query. Also, if this is a going to be a major SERPs change, it's important the breadcrumbs don't go too deep since as always, there is limited character space.

I'm looking forward to seeing how this alteration plays out - if you see any more examples shoot them to me @ChelseaBlacker or chelsea.blacker@baseonegroup.co.uk .
