Alternative to the Safety car commotion:My Take on it

(top)safetycar at Singapore Marina Bay Circuit leading Felipe Massa during the Singapore GP
Let the following be done -

• if there is an accident,

• yellow flag let be waved ,

Give all the cars two options-

1.Let all the cars get Align on the starting grid on their respective slots(the positions they were at wen the yellow flag was waved)
2.if u want to take an pit stop take one and Que up on the exit of pitlane after their respective pitstops(red light will be on...)
3.After the crashed/stalled car is taken out of the track..let the 5lights illuminate and go-off and let the race start again... for the people in pits they could come out once the train of cars aligned on the starting grid go off...maybe after 3sec after the 5lights go off.. 4.And safety car would only be implemented if the incident took place on the start finish straight itself...

Hence By the above rule,The usual commotion of the safety car trying to pick-up the race leader and also the commotion in the pits would end,there would be more transparency and things would be smooth!
