I've used the HUD available on the C5 Corvette, and it's no more distracting at first than any new car's radio, wiper controls, etc.

Once you've driven with it for a bit, it really does increase the attention paid to the road. Your quick checks for speed, gas, tach are instead diverted to mirror checks or just keeping your eyes on what's happening ahead.

That said, the Corvette's was a monochromatic subtle display. I'm not sure what the impact of full-color high-resolution information would be. One always has to be wary of the "ooo... let's watch the odometer rollover to the next 10,000" kind of distraction.

Do you have to check the petrol gauge so often, that it's a great boon having it on the HUD?

It's a C5 Corvette, yes.
