Those efficient cars are part of the gas engine alternatives I was talking about that make electric cars a red herring currently. I don't see a ton of good data out there for free but electric isn't the be all end all either. if I look at UK data published here: https://www.visualcapitalist.com/comparing-the-carbon-footprint-of-transportation-options/ https://www.visualcapitalist.com/comparing-the-carbon-footpr... it looks like the rough progression is if you go medium car to small car you cut your co2 output in half, if you then go to electric you cut it in half again. Electric car is not as good as rail and if you walk/ride a bike you are pretty close to zero. If you're still driving your electric car everywhere you are still outputting ~ 25% of the co2 of just driving your medium sized car. The zoning changes I am talking about would instead make the option of walking/biking (basically zero output) or riding transit (lower than an electric car if done right) an option for a lot of current trips, while lessening the kms needed to travel. If you want to throw in a ride share electric car for the many fewer car trips you then need you can do that and your co2 output will be cut very drastically with pretty much no hardship to you vs the alternative of having the co2 tax high enough to make the wide spread between gas and electric cars make sense to purchase an electric car (and the commensurate increase in home heating costs that much larger carbon tax would cause, among other large energy uses that would be more expensive).
