Switching from ICE to electric is a much smaller ask than switching from personal cars to... bicycles?
Sarcasm aside, I think this is why people have generally stopped caring as much. What we are being asked to do (buy new shiny things for some estimated small percentage decrease in lifecycle CO2 output) does not match the messaging.
FWIW I cycle almost everywhere.
Looking at American commute distances however, cycling, even with an e-bike, is likely not a reasonable option.
Bikes are awesome. I do 95% of my trips by bike. It's healthy, cheap, and has very low amortized emissions. Everybody can repair a bike with a small amount of training.
More countries/cities have to do bike-centric road design.
I get that a change in lifestyle is more difficult for the individual than a change in what we are buying. My point, though, was that only the former is going to have a much greater impact.
Good, working and efficient public transit still means having significantly less comfort compared to having your private vehicle. Pretty much the only exception is using the metro in a congested downtown area at peak traffic (still, your metro experience will also be degraded by the peak traffic), or perhaps if parking your vehicle will be very difficult. And i say this as someone in a rather big city in Europe who is currently only using public transit. And there is a lot of stuff that i'd like to do but i can't do since i currently don't have access to a car or motorbike.
People don't just want "useful", at least the majority of people in developed countries also want "comfortable", and "nice", and "easy", and "enjoyable". A peak-hour metro ride or missing your tram by one minute is none of that.
But hey, at least you get to keep 99% of your comfort while making 50% less emissions! (if it really is that much).
