This happened to my dad also..but he was the one that hit the car from the back..

It was at a traffic light, and my dad was very tired as it was puasa month and it was around 6 that time. He fell asleep and his foot slipped off the brake pedal (automatic car) so the car moved forward and hit the waja infront of him. He woke up n quickly got out of the car as the light was still red. There were 2 ladies in the waja but they didn't get out. My dad is 54yo! old man, retiring next year.. they were still scared. my dad went to the windows and said puan, sy terlanggar kereta puan.. kemek tu bumper tu..kreta saya crack sikit..just the bumper lining was cracked..minor damage..n all they said was kalau sikit takpe..but my dad said it was quite bad..when the light turned green, they sped off..their loss..i think to replace n repaint a waja bumper would cost around rm400 rite?..my dad didn't even have time to take down the number plate, otherwise he would've reported it..
