I fully agree that we need to make driving less attractive but in some of the cases, the push for more cycling infrastructure is having a detrimental effect on buses. Cardiff Council are actively trying to push people off buses by making them constantly slower and putting bus passengers as the lowest priority. For those unaware, see the photo below for what bus passengers have to contend with. You may think, that isn't as bad as it looks, what if I told you that is a two way bike lane? Why should bus passengers have to contend with this?
Given cyclists can use bus lanes, why is the focus not on more bus lanes and then everyone wins? Instead all road vehicles suffer including those which may be carrying lots of people. In some of the cases, the bike lanes aren't very well used either and it's ended up messing up the city and making things more congested for buses as well as motorists. The example that comes to mind is Tudor Street where they removed the bus lane to create the bike lane. 15 buses per hour use that section of road and these are now getting more delayed due to the amount of cars. The only way to remove the issue is ban cars and let's be honest, that is not going to happen and there will always be people who need to use their car a motor vehicle for some things. What can and should happen though is rather than create more traffic and hope people leave their car at home, you should be making buses more attractive. No one sits in traffic behind a bus and goes 'you know what, I may try that tomorrow, sit on that bus with everyone else, that will really help my day'. If however buses are flying past the cars which are sat in the traffic, you get jealous, exactly like happened with Joe Anderson, mayor of Liverpool (who famously rid bus lanes because he was jealous of watching all of the buses go past him while he was in traffic), and there is a lot more chance of someone going 'look at all of these buses going past me, I may get one of them tomorrow, they look so fast, I'll be home in no time'. Encourage people onto buses, not discourage them out of their car. Same end result, very different way of achieving that result.
