Also, wishing for a blanket increase in total number of busses by some huge percentage to avoid anyone standing probably sounds like a real nice plan until you have to pay for it... Capacity management isn't as easy as throwing drivers and busses at the problem.
Will they? When I drive I have to worry about parking and, you know, driving. If I take a taxi or ride share I'm paying on the order of 6x what the bus costs.
I think you're overstating the annoyance of standing on a bus.
Most buses are rated for "X Standing, Y Seated" passengers.
