First of all thanks for your answer! So I have an articulated bus, with two doors at the front and two doors at the trailer. As it already known passengers cannot enter the bus using the door at the trailer. But, some users have discovered a compromise to bypass this problem! They just modify the path and the passengercabin of the front part of the bus as it would have three or four doors. This comes at cost that passengers are seen clipping through parts of the bus but I can live with that!
