In all circumstances, safety is paramount at a motorsport event.
At each Formula 1 grand prix, if the weather conditions mean the medical helicopters can't fly, no track action can take place. Before the TV cameras are turned on and the spectators usually arrive, the sensors and systems around each track are repeatedly tested by the safety and medical car crews. It's all done to reduce the risk of the unexpected.
The coronavirus pandemic has changed the 2020 F1 calendar beyond all recognition. After the aborted Australian Grand Prix in March, there were serious questions regarding the viability of holding a season. Thanks to the efforts of many organisations - the FIA, F1 itself, the teams, and the national governing bodies and governments of the countries the championship is now set to visit first - we can look forward to track action finally starting one week from today.
