When thinking back, it seems that most of the time, Lego Town's racing subtheme featured a so-called "dragster" - a racing car with an elongated front.
This impression is corroborated by checking the actual sets: Brickset list
While I did not check for how long each of these "dragster" sets was produced/sold, if we assume a medium set lifespan (in the catalogue) of some 3 years, the succession of release years (1983, 1986, 1989, 1993, 1997, 1999, 2000, 2006, 2017) indicates at least until the beginning of the 21st century, there was at least one dragster set available at almost any time.
Now, I am not a car racing buff at all, so maybe I am missing something. Yet, while I have seen my share of car racing scenes on TV, and plenty of racing cars in museums of technology, I do not think I have ever encountered a "dragster" in real life. Therefore, my perception is that in the real world, dragsters must be an extremely exotic kind of vehicle.
Is there any known reason for why dragsters seem to be so overrepresented in Lego's town sets compared to other elements of the real world? (Or is it indeed my perception that is skewed, because dragster are indeed common sights a part of this planet's car racing subculture, and Lego is simply replicating that part of the world?)
