Germany has strong lobby in car industry

Hitting the nail right on the head.

Hey, no need to attack all your neighbours! ;)

How does this even work if you're in a wheelchair or have a stroller? Half of the elevators in Munich don't work and the other half is small and slow. It's a gamble every time. I literally calculate 15 minutes extra every time I take a long distance train to just go from Sbahn to the long distance trains at the central station because it takes two elevators and I have a stroller with me. And with a stroller you at least can somehow unsafely (also it is forbidden) try to balance it on the escalator. If you have an electric wheelchair you can forget about that. How are these more vulnerable people supposed to get to a new train station within 15 minutes?

Everything I mentioned in my comment is either something I experienced myself (multiple times), or I directly know someone who experienced it. If it reads like propaganda to you, I don't know what to say. It is what it is.

Punctuality is very much a mixed bag regional and S trains are usually pretty good here in Köln, there are delays of course but half of them seem to be idiots walking on the tracks which I don’t really attribute to DB.

Köln is what I'd say is a big (enough) city where you probably don't need a car, because public transport inside the city is at least decent.

But and this is the actually important thing that makes it all worth it, they run a ton of service, to a just insane number of stations. You can legitimately use it for all your travel if you just impose a time buffer about as long as the initial trip. From everywhere to everywhere in this country, usually for under 50€ if you just plan the slightest bit, or with the Deutschlandticket travel regio.

The amount of stations we have in towns of under 50k people might be among the highest in the world. The amount of people within x km of a station with regular (usually at worst hourly) service is enormous. The amount of track per person both in the country as well as company is staggering.

Sure, most cities have a station. But there are a lot of small towns or villages which have 1-2 bus stops at best. Where I live (~4,000 people), there's a bus coming about every hour, starting from 6:30am and ending at 8pm (!). Good luck going out in the evening when you have to be back before 8pm. I guess you could walk from the next bigger town, but that takes around an hour and after a busy day, you might not fancy walking for that long. In this bigger town there's a train station, and no it's not safe. It's a place where illegal activities are happening on a regular basis once it's dark outside.

It's not about comparing DB to the rest of the world. You need to compare public transit to cars/car infrastructure and then provide something that's at least as good if you want more people to use it. And where I live, it's not even close. Having to plan an entire trip multiple weeks ahead of time to get acceptable pricing is ridiculous and doesn't always work. Get sick? Unlucky, either no refunds at all or they're very expensive. And "Flex" pricing is ridiculously expensive, you can pay 150,-€ (and more) for a 2nd class ticket across the country. Sure, you can get a BahnCard 50 or whatever, but then it's still 75,-€ plus the cost of the BahnCard. Even when you're driving the car alone, fuel + wear and tear is usually cheaper than one "Flex" ticket. Traveling with 2-4 persons and you need to get 2-4 tickets, I found a route across the country (~470 km) where one ticket is 120,-€, so 240-480,-€ with 2-4 persons. 470 km in a car would cost 94,-€ in fuel assuming the car consumes 10 l/100 km (which it shouldn't) and 1 l costs 2,-€, and then you have 26,-€ left to 120,-€ for car maintenance caused by these 470 km. Travel with 2-4 persons and it's way worse. Sure, you don't have to drive yourself and that's a big thing, but the price gap is huge once you're 2 or more people, and you'd easily arrive two hours earlier by car, and that's assuming nothing goes wrong on the trip by train.

Another simple example would be the dentist for me. With a car, I drive 15 minutes (on a Sunday drive) to my dentist, checkup takes say 15 minutes as well, and back I go in another 15 minutes. 45 minutes is all it takes, I can basically do that during my lunch break. With public transport, I'd have to take the bus which takes 40 minutes (!) to the target location, add 5 minutes of walking time (so 45 minutes), and assuming the dentist takes longer than 8 minutes I'd have to wait about 40 minutes for the next bus to arrive, then take the bus back which takes another 45 minutes including walking back home. So 130 minutes, and that's assuming that the appointment perfectly aligns with the bus schedule. That's a huge difference of 45 vs 130+ minutes. I kind of value my time, you know? When traveling by car, I also have the option of quickly grabbing takeaway lunch on my way back to work.

Trust me, if it wouldn't limit me so much and cost so much time to go public transport only where I live, I'd be the first person to do it. I don't enjoy driving my car, I see it more as a necessity. I use trains for longer distances (when going on vacation or whatever), and if it all works out, it's an okay experience. Sure, it takes two hours longer and it's a bit more expensive even when traveling alone (I'm rather spontaneous most of the time), but I personally don't mind that as long as it at least works as advertised. But often, it doesn't.

I did a city trip with a few friends of mine this year where we travelled to a new city almost every day for about 10 days. We planned it in a way so that cities were no more than 2,5 hours apart. In theory...in practice, while that worked sometimes, we had two occasions where it took over 6 hours instead to arrive. Kind of sucks when you only have this same day to spend in the city, and it already starts to get dark when you arrive. On the trips that were in time, many trains were still completely overloaded and had non-working air conditioning, sometimes with 30 degrees C outside (you can imagine how hot it was inside the train). With a rather tight schedule and after days and days of travel, you'd sure enjoy getting a seat in a train, and working air conditioning.

Anyways, enough about my experiences. Great if it works for you, but as I said, if you/they want people to switch up the way they do things, there needs to be an alternative that's at least as good, but preferably better.

Part of the real causes of this trouble is that the railroad was privatized 30 years ago

That's the exact opposite of what the article claims

Or my favourite: One train getting canceled and all the passengers getting put into the next train to the same destination together with all the passengers already in said train. Which leads to fun times for everyone.
