In cities, it is important not to exceed **50 km/h** because **pedestrians share spaces with vehicles** and have the same rights. This means that both pedestrians and drivers must respect traffic rules and be attentive to avoid accidents.

- **Speed limits**: Within cities, the maximum permitted speed is 50 km/h. This is because, in the event of a collision, a pedestrian has a higher chance of survival if the vehicle is traveling at a lower speed.

- **Coexistence in urban spaces**: Pedestrians and vehicles share the streets, and it is crucial for drivers to maintain a moderate speed to ensure everyone's safety. Pedestrians should cross at pedestrian crossings and wait on the sidewalk before crossing, while drivers must yield when pedestrians have the right of way.

- **Additional precautions**: Drivers must be especially careful in areas where there are pedestrians, such as near schools, markets, and pedestrian crossings without traffic lights. Additionally, they should be alert to distracted pedestrians, for example, those using their mobile phones while crossing.

In summary, reduced speed in cities is essential to protect pedestrians, who share the space with vehicles and have the same rights on public roads.
