Its a tracked vehicle. How will you "drive" it when it's not supposed to leave the tracks?
Transport helicopters spawn in from the thin air. Why cant they let us have this? and why all of a suddenly so realistic regarding tour vehicles?
It's a game. Do you expect to see the helicopters taking off from some helipad and then flying to your location? That's a bad example and comparison. The tour vehicles are tracked. It would make no sense if you could drive them. That's now how vehicles on tracks work. If you want to drive a vehicle just use the ranger jeep. Alternatively the gyrosphere and the Jurassic Tour truck in the JW part of the game can be driven.
Considering they have a generic park worker DRIVING the automated tour vehicle..... eh em, we should be able to drive them as well. That or delete the park girl driving the dang thing.
Don't really see how it would be much different from just driving the ranger jeep around.
