I agree, but that costs a lot money. It costs $100/hour (this is likely low since I haven't checked in several years what inflation has done) to run a bus. That is one bus, even a tiny city will need more than 100 buses to just provide bad service, and would need 5-10 times as many just to give good service. If running buses were free everyone would have a bus every 5 minutes, with many different routes to choose from. Providing good places to wait for your bus is cheap by contrast, the cost of a single bus will upgrade many bus stops and the investment will last longer than the bus (though you need to maintain it)
You are wrong about rush hour. You need to provide good service all day, not just during rust hour. People who have good rush hour service and then a "family emergency" pops up mid day when they discover service is bad will go back to driving just in case that happens again. Plus running all day service at the same rates ends up breaking even - between staff willing to take less per hour, and good service enticing people to ride you can generally break even on your costs.
