A Le Mans-style start was used for many years in various
types of motor racing.

When the start flag dropped, drivers had to run across the
track to their cars which were parked on the other side,
climb in, start the car, and drive away to begin the race.

Such starts were very unsafe, with drivers possibly rushing
the process of fastening their safety equipment.

At Le Mans in 1969, Jacky Ickx, who always considered
this type of start to be dangerous, decided to walk to his
car instead of running. Taking the time to secure every
thing made him effectively start in the last position but
nevertheless, he went on to win the race.

This staged protest, and the death of John Woolfe in the
first lap, at the Maison Blanche curve, precisely because
he didn't fasten his seat belt, led to the running start being
abolished the following year.
Fun Fact - Le Mans-style Starts
Instead of the cars forming up on the grid before a race, they
were positioned one behind the other on the side of the start /
finish straight closest to the pits, at a slight angle known as
“ear of corn” or in “echelon” style.

At the start, the cars accelerated away one by one, beginning
a formation lap and bunching up before the race begins in
earnest.
