Personally, I don't focus on individual/free choices for the day-to-day at all, just policy. E.g. moralistic arguments about how people should ride bikes more are ineffective, you need actual on the ground changes in bike infrastructure to get real change for that sub-area. People trying to guilt each other constantly is just a distraction imo.

I had a car in the states and don't have one now in Munich. Did my values change? No, not really, I just moved somewhere where a car was much less necessary.

Now, I did still bike a fair bit in the states, but I didn't beat myself up over also driving a lot, because I recognized that the environment was not well set up for it in most places, which is how I got hit by cars twice the last year before I moved.
