The demand for second hand cars is already there. In 2030 people aren't going to turn around and say "wow hmm I all of a sudden want a second hand combustion engine car" and find themselves priced out.

Realistically, there's 20 years before the full impact of this policy will be felt at the bottom of the used car market, and the "poor" (who are a large group) will be hit by this law. That means there is 20 years to come up with an incentive or a solve.
