From VG247: “Cyberpunk 2077 lets you collect a range of cars and motorcycles and also allows you to take any vehicle you can see in the game. But what happens when you leave your main ride behind?
The same that happens with Roach, lead quest designer Pawel Sasko explained during our E3 interview. So basically, because those cars are equipped with AI, if you call it, you can see the car driving towards you. So you can see when it arrives, basically. You can see as your motorcycle arrives, you can see as your car arrives. So you can just leave it wherever you want, it can go somewhere, just call it, and AI makes it like bzzt!, he drives by and waits for you.”
