Sygic puts speed sign recognition on a phone.

Sygic, a navigation app developer, has introduced a new feature that allows smartphone users to use their phone's camera to read road signs, including LED temporary limits on motorways. However, the feature has limitations and does not work well in less than ideal conditions. Google Maps, on the other hand, offers a free and more user-friendly navigation experience, using data from millions of users to track traffic speeds and locate addresses and businesses accurately. While Google Maps generally provides precise speed limit information, it may not update 'smart' or temporary limits, so drivers should still pay attention to road signs. [Extracted from the article]
