Distance/spacing too tight

[balzbac]

I have noticed that FS Traffic lets other planes (including my own) onto the runway although other airliners are on short final resulting in go-around situations for 1) arriving planes when I am cleared to line up on runway or 2) my own plane when landing and another plane rolls onto runway right in front. I have always used ATC and was cleared to take-off/land -> but spacing is too tight. Can this be fixed?

I have a feeling this is rather an Asobo issue than FS Traffic but I'm not sure.
