The author concludes that a new traffic tax will not be effectively enforced when it is first implemented. This is because the tax requires a complex system in order to be enforced, and this system will not be ready until the end of next year.
Weβre given a necessary condition for the tax being enforcedβa complex new system. Weβre then told that the system wonβt be ready until the end of next year. We can validly conclude that the tax wouldnβt be effectively enforced until the end of next year, but we have no clue when the tax will actually be implemented. If it is implemented after the new system, then there is no reason to conclude it wonβt be effectively enforced. As such, in order for the tax not to be effectively enforced when it is first implemented, the author must assume it will be implemented before the end of next year.
