When I write positive stuff about cycling, it's not directed against cars at all - Cars are a great mean of transport, they are an important factor in our economy, it's fun to drive them - particularly when sharing a ride with multiple people and avoiding city centers.
But they are certainly not the best choice for every occasion. The vast amount of trips in Germany is carried out for private purposes averaging around 15km, while business trips are longer and possibly more justifiable.
When you study this graphic, you might find that your own municipality has a pretty low budget cycling infrastructure - which causes low adoption and low motivation for longer ranges (having no protected lanes, in a nice environment with fresh air, no smart traffic lights that would lead to increased safety and motivation). To make a comfortable 15km commute accessible for everyone, your municipality needs to upgrade!
In the Netherlands, we have long reached the "invite" stage and yet, they keep on investing (which does not mean that the infrastructure for cars is neglected - on the contrary, it is actually very good).
The existing infrastructure limits the target group of cyclists in Germany to the 4% mentioned below, who are often unpleasant combat cyclists thanks to the poor design of the infrastructure. Combat cyclists also often ride impractical racing bikes which it is very hard to transport things. So: Equip more standard bikes with 50l euro boxes and you can always transport things without any hassle. Having a "racing" bike is like buying a car without a trunk, which makes it nice for Sundays - but unsuitable for everyday use.
Once a really good infrastructure is created, the potential for aggression between cyclists and car drivers will be reduced to a minimum - because everyone has their own space and more people will be able to enjoy this "double competence" and learn to empathise with each other.
We should realize that there is infrastructure that does not disadvantage anyone and, on the contrary, can bring higher capacities, more life (and more turnover) to the cities and, at the same time, contribute to public health, the early development of autonomy of our children and the fitness of the elderly. Here in Germany, however, the car lobby is steering against it - possibly because they are afraid that it would work too well.
Again: cars are great, car sharing is great, car companies transforming into service companies: Amazing. Car-pooling: Super efficient. But individual transport has become too gross - people should reflect better on their personal traffic mix and advocate for building basic infrastructure that allows access for a wider audience! It's not about replacing or suppressing car owners - it's about giving a broader choice - about future-proofing the infrastructure, giving more equity & safety to the carbon neutral, less safe modes of transport resulting in healthy modal split that allows our cities to grow sustainably without adding lanes over lanes of Autobahn - this doesn't work (see cities in North America).
For 2021, I would like to see a reduction in aggression on German roads, and a substantial budget for really good infrastructure (not just unproteted cycle lanes right next to car traffic, which no one really benefits from).
