I dont think just by " Ghalti se hath lagne se gear R pe chala jaye "
You have to forcefully take it to R
Which i dont think anyone would ever think or try to do
Just like you said Ghalti se
Ghalti se N pe chala jayega
R k liye you have to move it slightly towards left and then up
Its a gate type auto gear lever and i dont think it will go to R just by a slight touch or by mistake
