Only for normal grid races :
now online leaders are in A world : why dont put them in 1st and 2nd positions on grid of
A world (for leader 1 and 2)
B world (for leader 3 and 4)
...
then complete 3th and 4 th positions grids with other racers. It's hard to race in A world because there are good racers in and sometimes , u have to share the road during whole race. when you start in C world on 1st grid pos, after 1st trun u got the entire road because slow racers crash quickly.
i think it could hard to do!
