So I hate drawing vehicles, so I had this idea early on that my character wouldn't own a car, so that I could avoid drawing cars.
But then it backfired, because she's on an island with no public transport, and suddenly, it grew into this whole thing, her trying to get around the island and whether or not she could find a ride/if the roads were safe for bicycling and it became this whole THING.
As a result, it turned into a running gag about how she gets between places and this has resulted in me drawing MORE trucks, cars, bikes and motorcycles than I ever would have if I just gave her a car and let that just be some unseen force in her life I never had to explain.
Moral of the story: never draw attention to the fact that your character doesn't own a car! This just causes more cars!
