Ets 2 may be a truck simulation game, but simulation games have a main vehicle and purpose. Ets is a game that bases its main vehicle and purpose on Trucks. However, other vehicles in traffic will increase the realism of the simulation. Since the bus mentioned in the suggestion is licensed, the same bus cannot be added to the game, but other or similar buses can be added to the game. These newly added vehicles will increase the reality of the simulation.
