Europe is much denser when comapared to US. You can do a lot within 300KM in Europe. Volvo openly states that the trucks are "to be used for regional transport and urban construction operations in Europe".
The trucks in question and the possible range is very well suited to this kind of operation.
Also, there's another important factor: Noise. Some European countries are more sensitive to noise than others. The Netherlands and Sweden comes to my mind.
These trucks will be a huge win on that front because a 44 tonne truck is not exactly silent, especially under load.
