If you had access to good public transport you could take a train for those 30 miles and relax, work or read instead of wasting time being focused on traffic. But if there’s too much supply of roads built for the purpose of everyone driving their car everywhere, there won’t be much demand to build something like that.
Biking and walking can then be for mid and short distances, respectively. But both will be dangerous unless there’s proper infrastructure for that. And again, not happening until they stop the over supply of roads.
And for hauling the dry wall, yes, use a car. Imagine how much nicer traffic and parking will be if most commuters who aren’t transporting big loads aren’t in private vehicles.
