5) Wikipedia: Poor Article “Bicycle License Plates (Switzerland)”

What are the weaknesses of Wikipedia’s brilliant achievement? How does this spiral of information errors arise? What is the «pleasure principle»? Why is Wikipedia’s requirement for citation so widely ignored? What fundamental role do first-class sources play in research? What important events are missing from the article? What are the results of contacting Wikipedia authors? What are the specific errors and inaccuracies in the Wikipedia article “Bicycle license plates (Switzerland),” in the “History” chapter?

The “pleasure principle”: There are plenty of sources. However, you have to have the “pleasure” to seek them out. 😉
