00:00To the naked eye, it's just a road.
00:02But to an F1 driver, it's a living, breathing, high-performance surface.
00:07A single mile of Formula One track can cost up to $20 million to build.
00:12Why?
00:13Because if the surface varies by even a few millimeters,
00:16a car going 200 miles per hour could literally take flight.
00:20The secret starts with the secret recipe.
00:23This isn't the asphalt on your driveway.
00:26It's a highly specialized mix of volcanic rock and polymers,
00:30designed to grip tires at extreme temperatures.
00:32They even use 3D laser scanners to ensure the surface is perfectly flat
00:37before the first car ever touches it.
00:40Halfway through.
00:41Welcome to Fact Space.
00:43If you're amazed by the science behind speed,
00:46hit subscribe, share this with a car enthusiast,
00:49and comment which track you think is the hardest to drive.
00:53Then there's the safety.
00:54The TechPro barriers you see are designed to absorb the energy
00:58of a 200 miles per hour impact in milliseconds,
01:01turning a potentially fatal crash into a walkaway moment.
01:05These tracks aren't just built for speed.
01:07They are built for survival.
01:09From the volcanic rock to the laser-leveled finish,
01:12an F1 track is the ultimate masterpiece of engineering.
