I have seen the film in 2002 or 2003 and remember very little:
- the genre was “thriller”
- there was a mother with one or two children
- the father or stepfather of the children was an evil man (likely a severe abuser, but I don’t remember the details)
- at the very end, he rides off the cliff with his vehicle, like the truck driver in Duel (1971)
Thank You in advance
