Find some old on-board footage from the Le Mans 24 Hours on YouTube, and just marvel as the cars speed through the Porsche Curves. Not just at the start of this famous sequence, but also the end. It's almost as if the drivers are racing through a tunnel.
There's no room for error. A small strip of grass is all that stands between the asphalt track surface and the concrete walls through the final right of the Porsche Curves and the following left-hander, formerly known as Karting, now named Corvette.
That was the case all the way into the present decade. But no more. The walls are now almost out of sight beyond a wide expanse of mostly asphalt run-off.
