thats y u must make sure u 'accidentaly' reverse on the bikers legs if he's at fault. sometimes these fella's simply ride like their grandmothers/fathers road. if he's not at fault, then ok lor.
but the worst if the motorrider got no insurance, then u cannot do anything but either pay yourself, or hantam the rider until money fall from his ass. thats y when i see motors, i always extra careful. use horn very sparingly....
