I want to read a novel about building a car and then racing it or driving it all around the world No bl No romance if possible No simp mc
Hmm not making their own car and not driving a car too, but Kino no Tabi is about MC's journey riding on her motorbike going all around various countries and encountering the people there. Definitely not BL and no romance too, maybe you could give it a try if you haven't
How about anime or movies? Like Initial D, and I think it also has a manga. And there's the Fast & Furious Franchise Movie
