Google likes challenges in automating and give you the most relevant information you requited. Identifying your current location is the most important factor. We are not only googling to find out the definitions, code example, how to articles, but nice restaurant, shop to buy a gift and so on. If Google is not detecting your location accurately then you have options to correct it and get a better results.
This is what Google says about it
"We do our best to automatically detect the most useful location, but we don’t always get it right—so in some cases you’ll want to change the setting. At other times, you may want to change your location to explore information relevant to another area. For example, let’s say you’re at work in Mountain View and you’re making plans to see a movie in San Francisco (a common occurrence here at Google). You can change your location to “San Francisco” and search for [showtimes] to find movie listings in San Francisco or search for [restaurants] to find places to eat before the show. Similarly, if you’re planning a trip to Hawaii, you can change the location to “Honolulu” and start exploring the [weather], [hotels] and of course the [beaches]. The location you set can be as specific as a particular zip code or as general as an entire country, but more specific settings generally lead to better search results."
Google detect your location by IP address or the Google Toolbar My Location feature. If your internet service provider is in another location and they haven't give your a public IP address you might notice that your current location is coming up as your service providers location, not yours.
If you use Google to find places around you or planning your holiday and need to find out the shops and restaurants before you go there, this will be a good option to use.
