It is easy to say what Athens needs: less cars. Better public transportation, more & monitored bus lanes, bike lanes and downtown-charging for private cars (parking fares, tolls). We must act now! The crisis is also an opportunity: there are less cars downtown so there is space for the necessary changes. The Panepistimiou str. transormation is an excellent start. Bus lanes around it all over the center is the second step. Buses will share their lanes with bikes until special bike lanes are made.
