The safety and rules here are quite different to Oldenburg. Bikes ride on the road with the cars instead of elevated next to pedestrians. In many roads there are no separate lanes and you have to share a lane with cars. The rules say that you should keep as right as practical but the safety tips on several websites say that if you ride without taking as much space as you need, the chances of getting hit by doors of cars parked on the road or even cars entering the road from driveways is much higher – as drivers are going to look further into the street for other cars and could easily miss a bike. But on the bright side, Google maps shows which roads have bike lanes and recommends very different routes to what you would take if you were driving a car based on safety.
