Car makes sense, but not the gym.
You can work out your entire body with almost no equipment (pushups, squats, bridges, holds, handstands). A pullup bar (park or the door jam kind) for pullups, dips, and leg raises is pretty useful though. For cardio, you can bike, run, do circuits, jump rope, jumping jacks between sets. I agree that it is easier to work out when you can go some place to do it, but that is a pretty minor excuse.
