This is the Microsoft tech that's fueling NASCAR

A line of cars as far as the eye can see snakes between the big rigs that carried them to the race. There's a buzz of excitement as crews scramble to make last minute adjustments as officials begin measuring every inch of each car to make sure no one is cheating. Frank Prendergast, a NASCAR engineer working on vehicle inspection tools, pulls out a Microsoft Surface Pro tablet and calls up the Mobile Inspection app. The app, also developed by Microsoft, collects and verifies visual inspection data. It's cut down a process that typically takes six hours to just three, and Microsoft claims the app has already saved 20,000 sheets of paper.
