How to solve a problem the German way:
1️⃣ build a new bike path
2️⃣ block the pavement with equipment for air-pollution monitoring
3️⃣ do not reduce car traffic, but put six huge vacuum cleaners next to the monitoring station onto the bike path
4️⃣ set up 14 traffic signs that legalize riding on the pavement, whereever a vacuum cleaner blocks the bike path.
5️⃣ problem solved! SUCCESS!
