What's the worst collision or crash?

[Negus]

I once saw a orange Civic SiR literally wrapped around one of the pillars of the ortigas flyover back back in 2004. I presume the driver and anybody who's with him/her is dead.

Another one, involves a jaywalker and an FX taxi at the Commonwealth flyover near Iglesia ni Kristo. When the FX is about to hit the man, I just bit my lips in anticipation. The man flew over 10-15 feet. Then rolled and ended up in the inner most lane. I also presume he's dead.
