5. Train/Bus
This is a very generalised point, however I didn't think it was fair to compile a top ten list without some sort of acknowledgement to other forms transportation. Little is known about how significant buses will play in GTA V. Many of us though that GTA IV would allow us to travel the city by catching the bus, maybe quick skipping like you could with taxis. This wasn't the case. All we could do was car-jack them. That hope is renewed for the latest edition. It's not just being a passenger that has caught the eye, the new buses look less bulky and perhaps a tad quicker. You could now hop on one of these and pretend you're Keanu Reeves from 1994 film Speed.
