So, in your case, you only really need to make more to afford a walkable lifecycle if you still want to own a car and have the option to use it to drive to places outside of your walking distance. Of course, completely moving to a lifestyle where all travel is public trasit and airport-based is tough to achieve, but it could be a worthwhile price to pay depending on how often you travel and where (since the time investment is also high for cars in the U.S. with how far apart each city is from the next).
