In front - YES
Behind - Don't care

That is supposed to be the message that it sends to other motorists. Kaya ang hirap satin dami gumagawa ng sariling 'rules' or 'norms' sa daan.

Sadly, norm na nga yun dito saten. If you are doing that on purpose, pero you are still careful on switching lanes, well that's fine. A lot of those who knows them learned to accept them. Besides di ka din naman magpapatakbo ng mabilis kung makita mo sa harap mo puro naka hazard. Nacocompromise lang nyan is yung mga swerve pa din ng swerve kahit naka hazard kaya manghuhula talaga yung kasunod.
