2. Convertibles
In all of their recent revelations, R* have been keen to point out that GTA V features the biggest roster of vehicles ever included in a GTA game to date. In the above shot from the first trailer - again for the first time in a GTA game - looks to feature convertible sports cars and what's more, you'll likely be able to activate the roof at the press of a button (as the guy above clearly does in the trailer). Okay, so maybe this won't have a massive impact on actual gameplay (although maybe it will, should you be chasing down a vehicle with one of your companions riding shotgun for example) it's definitely a nifty, completely new
potential mechanic (R* have neither confirmed or denied it, so I'm still forced to treat this as specultion) that promises to add even further texture to an already pretty sweet mechanic.
