A driver cowered in fear and disbelief as an inflamed attacker beat his car's windscreen into shards of glass and blood on Thursday night.

Brenton Davey, 31, of Footscray, was driving home at 9.45 when three monkey bikes pulled out in front of him on the Ballarat Road highway in central Sunshine.

Mr Davey blasted his horn as the four riders who, without helmets, weaved in and out of traffic at high speed.

When he reached the Anderson Road intersection, the bikes pulled up behind him with their lights off. The men dismounted and tried to wrench open his car's locked rear doors.
