15% is a significant dent. It's 15%! Even half of that is significant. And I'd sooner say we transition to encouraging just about any other kind of transit via our city and infrastructure design (efforts are ongoing, so it's not like no progress has been made) rather than just encouraging everyone to switch to an electric vehicle, but there are all kinds of benefits to restricting vehicle traffic in city centers besides climate change too, probably helping them to sell this policy. It's still a reduction that helps climate change, but it's one of those ones like straws and plastic bags that are much easier to legislate even if it's not the largest reduction that could be made. I guess I just disagree that anything other than the largest slices of the pie are worth putting any focus on, because if it was easy to reduce those large slices of the pie, we'd have done it. Even those large slices can probably be broken up into smaller slices, of which some may be easy to deal with.
