one of my personal favorite toriyama genres, “a bunch of people in a tiny but highly-detailed car”
post good-ass toriyama art in this thread
toriyama will (rightfully) be a legend for dragon ball, but something he couldn't showcase in the manga was his astounding vehicle design. the dude had an extreme passion for blending sci fi with older vehicles and he took advantage of that any time he had the opportunity to do illustrations
highly recommend looking these up if not even studying them. toriyama's sci fi work is inspiring
