These include a number of other important points, notably with the Safety Car.

In future when the Safety Car is deployed no car is allowed to go to pitlane to refuel until all the cars are all lined up behind the Safety Car and the message "PIT LANE OPEN" is shown on the timing monitors. A 10 second time penalty will be imposed on any driver who enters the pit lane and whose car is refuelled before the second message is shown. In some cases it may be worth a team taking such a penalty because the advantage gained will be far greater, but we will have to see if that eventuality ever occurs. If the Safety Car uses the pitlane the cars may not stop until the "PIT LANE OPEN" message appears.

In order to stop gamesmanship behind the Safety Car and avoid possible accidents there is a new rule that states that "any car being driven unnecessarily slowly, erratically or which is deemed potentially dangerous to other drivers at any time whilst the safety car is deployed will be reported to the stewards".

There will also be a change to the way a Safety Car period unfolds as there is now a new message which will say "LAPPED CARS MAY NOW OVERTAKE" which will mean that all cars running between the leading cars will be allowed to pass the Safety Car and gain back a lost lap. They must "proceed around the track at an appropriate speed, without overtaking" and then rejoin at the back of the field.

Policing this will be interesting as lapped drivers will potentially gain a huge amount with the new rule and are not likely to dawdle.
