Strangely, it appears the terms "legally blind" and "blindfolded" equate to the same thing. The Guinness record and Extreme Sports say "blindfolded," but Newman and the man who held the record before him, Turkish pop singer Metin Sentürk, are legally blind and neither of them wore blindfolds during their record attempts.
No matter – the real point is that Extreme Motorsport is casting about for a driver to set a new record. The could-be-shady part is that Extreme is pretty vague about what's involved; they'll provide the car or the motorcycle, but you have to "choose a charity and pledge to give them all the funds you raise above the entrance fee and for any other personal expenses you may need to participate in the challenge." Extreme doesn't give any indication of how much that entrance fee might be.
But if you're over 21, no taller than 6'6" and no heavier than 260 pounds, it's at least free to request more information. You can watch Newman set his land speed record in the video below, but if you really want to best him you'll have to beat the water speed record he also set last year.
