any idea why this fellow do this?

according to the thread owner in the forum, they were going up slip rd to PIE then tis bus tried to overtake him/her

but cant tell why aft overtaking must force the car to the shoulder...

To be fair, from photo very hard to tell who is in the wrong. Last time I used to take photos of 'idiot parking'.

Now I don't do because got one time my own friend kenna "photo'ed" for that. But he told me the situation then I realised why.
