Thanks! Completely fair point. In fact, I already thought of it: my idea was to add accidents and/or protesters blocking the road sometimes, but I ran out of tokens because the code I wrote for the game is horrendous 😅 (Pico8 limits how much code your game can have).
To compensate a little, sometimes there are clusters of bones on the sidewalk, which I think might incentivise the player to move there momentaneously. But I reckon that's definitely not enough, and if code tokens were not an obstacle, I would have added blockers on the road lanes to force the user to move.
