Public transport interest, changing obsession on means of it

I have a general interest in all forms of transportation with Asperger-like tendencies. Cars, buses, trains, planes even space travel. I also enjoy public transport, the fact that its organized into distinct systems, timetables etc is very enjoyable for me.

However, my problem is that instead of enjoying the diversity of so many ingenious modes of transportation devised by humans over the years, and used differently in different parts of the world, I become obsessed with one mode of it, for example rail travel, celebrate countries and areas where it is widespread, like Eurasia, and feel annoyed that in other places, like the Americas, it's not as widespread. If I'm in a "rail phase" for example, I consume vast amounts of information on the subject, while thinking that other forms of transport are inferior, and that things like low-cost flying and widespread ownership of automobiles are bad, because they make rail travel less important than it was, say a hundred years ago. Two, or three weeks pass, then I enter into another phase, for example a "bus phase", then I glorify buses and hate trains, celebrate the Americas for widespread bus travel, loathe Eurasia for having widespread train travel instead etc.

So my problem is, that despite being interested in all forms of transportation and consciously and rationally liking the fact that transportation systems and solutions are so diverse around the globe I can't enjoy all of it, because my OCD makes me periodically deify one form of transport while demonizing others, and the focus of this deification/demonization seems to change about every 3 weeks or every month.

I'd say that it's typical aspie behavior to narrow down our interests to even more specific aspects and sometimes move between different aspects. It would be more surprising in my view if you had a general interest in transportation.
