Thank you for this! Very exciting that we’re so close.

Would you please clarify how the width of the new, sans-autowidening roads is determined? Is it just 1 day’s worth?

And would you clarify the relationship between the width of the road, the color of the goal, and the number of days till derailment? Is it just that the lanes correspond to different colors and the colors represent different numbers of days till derailment?
