Is an iPod more dangerous for your ears than a NASCAR race car?

Anyone who’s ever been to the track knows that racetracks are loud. Quite frankly, it’s one of the things many people (including me) like about actually being at the track as opposed to watching on television. But could that noise be doing your hearing permanent damage? Is it any worse than any of the other sounds we encounter on a daily basis?
Let’s go to the data… […]

NASCAR Drivers’ Risky Behavior and the Peltzman Effect

The introduction of automotive safety innovations is usually accompanied by concern about the side-effects of those innovations. For example, when seat belts were introduced, people worried that the belts would keep them from getting out […]

Daytona, Catchfences and Flying Cars

Track barriers originally were erected to keep cars separated from spectators. In addition to concrete walls to prevent the cars from driving off track, debris-spewing accidents necessitated fencing to contain airborne objects.

Catchfences should have the same properties as walls, but they can’t block the view. Chain link fence is a good compromise: It’s cheap, plentiful, easy to put up and surprisingly strong given its high visibility.

Chain-link fabric is an elastic metal mesh. It can give in two ways: gentle forces cause the mesh to deform. The diamonds stretch out of shape, but when the force is removed, the fabric springs back to its original shape. The fence can also deform by stretching the wires that make up the mesh. A large-enough force will break the wire entirely. […]

Cooling Fuel: Safety or Performance Issue?

Temperatures at the Dover race were unseasonably high. Kurt Busch’s Stewart-Haas 41 team was told by NASCAR officials to remove “heat shields” from their fuel cans. The cans (shown at right) have an 11-gallon capacity. Not shown […]

Running Tracks Backward

The All Star Race, let’s face it, is a series of gimmicks strung together in the cause of entertainment. Not that there’s anything wrong with doing that. It’s what every sport does. People like home runs? […]

A Band Aid for NASCAR’s Tire Bleeding Problem

There are three things you don’t mess with in NASCAR: engines, fuel and tires.

Tuesday, NASCAR handed down a P5 penalty – the penultimate penalty on the books – to Ryan Newman’s 31 team. Crew Chief Luke Lambert was suspended six races, fined $125,000, and Newman and his owner Richard Childress were each docked 75 points. The tire specialist and team engineer were suspended for six races as well. RCR is appealing the penalty, but I wager they’ve got an uphill battle.

NASCAR’s made its stand loud and clear in the last few weeks. Tire bleeding will not be allowed. If you persist in trying, they’ll come down hard on you. […]

The Science of Firesuits

If you were to poll racecar drivers about safety, I bet the majority of them would say the scariest situation isn’t a crash.

Two fears you have as a race car driver: one is being on fire and two is being T-boned in the driver door – everything else you sort of accept. –Elliott Sadler […]
