Magic Earth is closed source but it claims it respects the users privacy, it uses open street maps and it has decent traffic data for navigation for some countries. It also has the advantage that you can configure it to stick to the original route if you prefer. This is very important for me because sometimes I want to take a scenic route, or just routes I prefer but that are not necessarily the fastest.

dont get too attached to that computer where you installed it, under communism is no longer yours.
