Demanser, who holds a two point lead after the first of three rounds in the Hawke's Bay championship raced on November 1, didn't want to comment on Saturday night's hit in case it jeopardised his Speedway New Zealand judicial hearing.
This incident stole the limelight from the evening's three feature events - a 16-car Hawke's Bay Saloon Championship, the Strong Family Cup in a 19-car stockcar class and the Best Pairs in a 16-car streetstock field.
A first heat relegation for contact ruined Hawke's Bay driver Steven Martin's hopes of a fourth Hawke's Bay Saloon Championship title. Two second placings saw Martin finish one point behind the Gisborne pair of Dan Cook and David Moorcroft.
Cook and Moorcroft were scheduled to have a four-lap run off at the end of the meeting to decide the title but Cook won the title when Moorcroft withdrew with mechnical issues.
Hawke's Bay clubmates Jason Penn and Michael Smith shared title honours in the Strong Family Cup after their run off was cancelled because of the late finish to the meeting. This was Smith's first taste of title glory.
One Hawke's Bay-Gisborne combo of Ben Yeoman and Brendon Gooch pipped another of Glen Shepherd and Travis Gooch for title honours in the Best Pairs.
After winning his first heat from the back of seven-car field Hawke's Bay's national TQ class champion Duane Todd's racing ended in the second heat when he was involved in a spectacular collision with clubmate David Wilson.
