Well, since politicians are the ones passing the laws we still have to have a way to force them to do that.
Over here in Germany our notoriously car-loving Minister of Transportation has been in breach of law for years by now, refusing to put in place measures to reduce CO² emissions in the transportation sector.
And last time I checked they wanted to change the law so the overachievement over other sectors can excuse the failure in others. So no need to do something in the traffic sector, if other areas performed better.
Not sure what the current state of this plan is, but I would assume they didn't take it back, which would seem the only reasonable thing to do🤷♂️
