That's not true on a major avenue that serves 10 different routes, which combined have a frequency of one every couple of minutes.
Also, it doesn't help to make bus stops more spaced, and you may not want a bunch of express routes that skip most stops, because another purpose of buses is to help people with difficulty moving (like the elderly), for whom it's not a 5min walk.
You just want to make the service available, and as good as possible, without incentivising people who could just walk to use it.
Because the actual goal is to displace cars (not walkers, or cyclists, or…)
