The North American approach (because Canada is guilty too) to transit is to just throw a bunch of busses at the problem and act like they’ve “solved traffic”.

Nobody thinks they're "solving traffic". In most of North America, buses are seen as transportation for poor people. Cities feel like they need to supply them because poor people need to get to their jobs, but it doesn't have to be a good solution.

In Switzerland where they actually do try to solve traffic with buses, those buses have their own dedicated lanes, their own stop lights, etc. Plenty of rich people still drive because it's a status symbol or something, but buses, trams and trains are the fastest way to get from A to B. Cars are forced to yield to bus traffic. The result is that buses are fast and predictable, so everybody's happy to use them, which means they get increased investment, which leads to even better bus service, so even more people use them, etc.
