I read the novel for this, and had a pretty good time. It actually caused me to come up with my own (slightly different) isekai premise. A man is struck by a semi-truck and dies, but this person gets the draws 4 of the cards of fate and reincarnate in another world. The cards he draws are Sustained By Mana (no longer needs to eat, drink or sleep as long as there is mana in the air around him), Wellspring (instead of only absorbing mana like a regular person, he acts as a font of mana, which synergizes with Sustained By Mana, since he generates mana that his body then consumes, although Wellspring generates more mana than is required to sustain him), Warehouse (has access to an inventory space of 500ft x 500ft x 50ft; living things can enter and time is not frozen), and Imitation As the Sincerest Form of Flattery (Reincarnate as that which killed you). That last one, it's important to understand that if a man with a sword slashes and kills you, or a man with a gun shoots and kills you, you were killed by the man, while the weapon is simply the tool with which the deed was done. Therefore the protagonist would reincarnate as a human being. But upon his regaining consciousness, he discovers he is not a human, but a semi-truck. This is because, it is revealed by the goddess who reincarnates him, when he was struck and killed, the man behind the wheel of the truck had suffered a heart attack and died, causing the truck to veer off course and hit the MC, and therefore the truck itself was the killer and not the driver.
The MC is in a world with stats and levels and such, and despite being reincarnated as an inanimate object, can drive and steer himself. And by running over small and mid-sized monsters, he's able to gain exp and purchase upgrades for his truck body, like armored tires and headlights that fire light magic. And once his level is high enough, he can manifest a human form within his truck-body. He eventually rescues a group of adventurers who were in a bad way with a swarm of monsters, driving through the swarm and getting the adventurers into his trailer (which is also his Warehouse), and teams up with them to go touring around the world, fighting monsters, helping people, and generally having a light-hearted adventure.
