This is true, although I have to say as someone who doesn't own a car, good public transport can avoid most of those issues. I live in a small-ish city (500K - 1M pop, depending on how you count it), and I can get pretty much anywhere I need to without worrying about schedules and certainly without worrying about strikes. The biggest issue is getting out of the city - that's when it's usually more important to worry about schedules, but it's still mostly doable - and occasionally transporting furniture or something like that.

On the other hand, the benefits I get from that public transport are incredible - it's cheap, it's always there, it requires minimal logistics in groups (no trying to figure out who goes in what car and needs to be dropped off where at what time), it works regardless of my level of inebriation (admittedly I've not pushed that one to any sort of extreme yet), it's safe enough for children to travel independently (no dropping them off and picking them up), and it's largely accessible for people with difficulties walking or moving about.

I think a big part of the issue is that people have tried out poor public transport infrastructure and recognised - often correctly - that their car is way better for them. But good public infrastructure can often be far more convenient than cars, it just requires people to be motivated enough to build and finance it. A neighbour of mine didn't notice his car had been towed for a week because he used public transport so much and so rarely touched his car. When he'd parked his car it was fine, but then they needed to block of the street to do some work somewhere, and he didn't notice they'd confiscated all the cars there. That's the sort of effect that good public transport can have - so comfortable that you can forget you even have a car.
