What about a tiny plane (smaller than the buggy)? It could go 300 mph and accelerate quickly, it would not stall, would be weightless, and highly maneuverable. It would also have a feature when holding down space to "hop a few feet to left or right very quickly. It would have high-powered laser-locking with a wide locking area, but very short range, rapid-fire lasers. The overall effect would be a vehicle that could zoom around maps easily without being too difficult too fly through narrow spaces like buildings and forests and not present a huge target. It would have to dart in very close to targets to hit them but could immediately dart back away.
