When the Shelby GT350 and GT350R Mustangs come out, they're going to cause chaos on and off the road. The furious Mustangs are purpose-built track cars and have the technology to aid drivers in owning any track day. For example, Ford's new Performance Shift Light Indicator isn't like other HUDs. It's an intuitive piece of kit that will actually help drivers get the best out of their GT350 Mustang. The system has three display modes: "Tach, Track and Drag."

The first "Tach" mode lights up sequentially as the revs build. "Track" mode makes the lights illuminate from each end towards the center and then flashes at a preset shift point. Lastly, "Drag" mode only flashes at the shift point to keep things clear.

While this system will surely help on the track, we're not sure if it's necessary on the road. What do you think? Would you like your vehicle flashing all sorts of lights at you while you're driving?
