Which is also why building bigger roads, generally doesn't improve traffic issues. Given the options available, people will generally choose the most hassle-free route. If public transit improves, more people will take it, which will improve road traffic. If bigger roads are built, less people will take public transit, because roads can handle more cars before the traffic factor forces people to use alternatives. This breaks down a bit outside cities where the only option is to drive (no buses, too far to bike or walk), but remote areas don't usually have traffic problems even with low capacity roads.
