> Maybe design cities to be walkable and bikeable

Why does everyone suggest this like it's easily done and the only reason that we haven't is due to lack of intelligence and/or will?

It's not. It's an effort that will take decades, cost trillions of dollars, and will face both legislative and legal hurdles.

Besides, with individual trait recognition technology and smartphones, you'll just be tracked regardless. You have to hold leaders to account for this sort of abuse of power.
