Formula One's governing body has hailed drivers for their 'invaluable' input ahead of a teams meeting on Monday that will put forward proposed rule changes to improve racing.The sport has undergone the biggest change in decades on the chassis and engine ​with new power units that are split roughly 50-50 between electric ‌and combustion ‌power.Drivers have, however, complained about the impact on racing and ​raised safety concerns from having to ease off the throttle early and coast into high-speed corners so the combustion engine can recharge the battery.
