Not my searches. If I need something location sensitive, I have no problem adding the location in the query.
As an aside, whenever a new search engine comes out, or there is an update to an existing one (Bing, mostly), the test I always use is to search for "python" with no other search terms. If the results are dominated by articles about the animal (as was the case with Cuil a few years back) then the search engine and its weighting choices probably isn't a good fit for me, personally.
Google will increasingly give you better results the more you use it because of data-tracking and search personalization.
