As of 2009 teams are limited to 15,000 test kilometres during a calendar year. Young driver training and promotional events do not count towards this tally. Testing can only take place at FIA-approved sites and, ahead of a session, teams must inform the governing body of their schedule so that an observer can be appointed if deemed necessary. Testing during the race season itself is banned (from the week preceding the first Grand Prix to December 31), with the exception of a small number of straight-line aero tests.

The famous Le Mans start and the less famous Tourist Trophy start were some of the few instances where running to your car and starting the engine was part of the race. In most other forms of racing the engines are running or started on the grid somewhat theatrically as at Indianapolis prior to one or more pace laps. The modern Formula 1 cannot start on its own and their unique standing start can only happen after the cars have returned to the grid following a formation lap.

Earlier race cars did have starters but as we can learn from the following turn of the century recounting by Charles Jarrott that all was not so simple ... (Frank) Wellington who was an expert on ignition burners (so he informed me), then proceeded to light the ignition lamps for the motor. His methods were drastic, novel to me, and terrifying to the bystanders. There was rather a big blaze, but, as he explained to me afterwards, that was a detail, and it really was not dangerous. Anyhow, when I say that he turned on the petrol tap, flooded the whole of the engine with petrol, turned the tap off, lit a match, dropped it inside the bonnet of the motor and then ran away, one can imagine that my criticism of his expertness was somewhat more forcible than my expression of the word "primitive." And having assured the bystanders that the aid of the fire brigade was not necessary, and the flames having subsided, we got the burners to work with the aid of some methylated spirit, and proceeded to start the motor.

Mechanician - In the early days of motor racing one mechanic or mechnician as he was know would actually ride next to the driver during the races. S.C.H. Davis served as a riding mechanic to Count Louis Zborowski in the 1924 French Grand Prix:

The art of cornering has many aspects but it all starts where the tire hits the road in what was once referred to as slip angle and is now illustrated in the form of a traction or friction circle.

In the diagram at right the roadway exists in the x-y plane with the direction of travel illustrated by the headlights. The vehicle cornering to the right shows the tire rotated at an angle from its actual direction. This is the aforementioned slip angle. The use of a circle describes how cornering, braking and acceleration forces come into play and using modern data acquisition these forces can be graphed.

A tire can generate horizontal force where it meets the road surface by the mechanism of slip. That force is represented in the diagram by the vector F. Note that in this example F is perpendicular to the plane of the tire. That is because the tire is rolling freely, with no torque applied to it by the vehicle's brakes or drive train. However, that is not always the case for often the is either accelerating or braking.

The magnitude of F is limited by the dashed circle which denotes the maximum level of adhesion. The diameter of this traction circle is affected by many things, including the design of the tire and its condition (age and temperature, for example), the qualities of the road surface, and the vertical load on the tire.

Communication between drivers and their mechanics has always been critical to the success of the team whether the mechanic or mechanics were in the seat next to the driver or in the pit. Now that riding mechanics have been banned same for the occasional salutes to fellow racers who forget to check their mirrors communication in now limited to drivers and their pit crew. Before two-way radio this was accomplished through the use of hand signals, flags or sign boards.

Alfred Neubauer was famous not just for his girth but for the host of flags he carried to each race. One drawback though was that the other team or driver could also see these signals, sometimes to their distinct advantage. In response some hand signals were added that could be changed depending on the circumstance similar to the signs used in American Baseball without the theatrical spitting and grabbing of one's crotch! At the beginning of each race Neubauer took his place at trackside, a black and red flag in his hand. An official seeing this strange sight tried to have him removed but to no avail. There is even a photograph of Neubauer at the front of the grid holding up 4 fingers to signal four seconds to start. Amazingly all eyes are on him rather than on the starter! From that moment on a race without Don Alfredo could not have been very important. Woe betide the driver who should happen to miss or ignore these signals. The driver trying to keep his car on the track at speeds of over 150 miles per hour was left to cope.

The introduction of two-way radios, computers and electronic monitoring gives the team and driver real-time information regarding the race as well as the health of the car. While electronic control from the pits is forbidden they can inform the drive to make an adjustment from the cockpit. To top this of the teams also have the latest weather information should a storm be brewing.

As if this information overload is not enough live feeds have now allowed the viewing public, happily sitting on their couch to listen in while the crew exhorts their overwrought driver that the moment had arrived to go all out to catch and pass the car ahead. It's doubtful if this sorry spectacle would have ever been directed at a Tazio Nuvolari or Gilles Villeneuve had the technology been available. They knew nothing else.
