A problem with a points-only or points+trivial fine system, is that although it might scare straight a generally good driver who occasionally has a heavy foot; it only becomes a deterrent for persistent recidivists when they near the disqualification barrier. Even then, it's only a deterrent if driving whilst disqualified carries a heavy enough penalty.
