This tells me that his level of understanding of the wide range of cars and features. Are their bad cars and bad UIs, yes.
However, as someone who has been driving for 30 years, cars are better in every way now than they were before (From a driving, efficiency, reliability and safety perspective).
The only thing that is arguably "worse" is self servicability. However this is a function of complexity that exists throughout all technology.
Also, these features that everyone on HN complains about.. they are being added because the general population wants them. There are very few people who would buy a car without any screens, ui or infotainment. You wouldn't save any money because a lot of this tech is required for saftey and would be bespoke thus costing more.
