But the main difference is that if there is a collision the pilots wouldn’t receive any injuries and so it makes this sport absolutely safe. That is why many people believe that the drone racing is the racing of the future,

I don't agree with you on this because:

• First of all there's a big size difference, an F1 is like 10 times bigger than a drone
• Secondly, the races aren't incentivized by the same interests F1 is watched by people loving car brands which builds legendary and very performant cars so if there were to be an alternative it would a competition of flying cars
