In 2008, when we crossed babusar, we saw an old corolla car crossing the pass, though it was difficult for the car, but he dragged the old machine through it...
and last year when we were in besal (in cultus), our driver told that he can cross babusar in cultus if the road is open but that time pass was closed... you have to be extra careful and exceptionally skilled specially on some narrow bridges which are made of iron beams or wood planks, specially the one just before besal and the one just before lulusar lake
