@leungbook :
lunar is just trying to explain that this has not been taken into account when programming the select option, this is not the way it was thought. ti was just to make each lap a attempt, because you had to save the turbo from previous lap.
that's why he calls it an exploit. i think SL just imagined it as players would press select only once.
now they see it, and maybe fix it, what would become all records achieved using this?

of course, the thing was to obtain the best time, and select-turbo-select helps.
but now those records are on the ladder, they must leave it, to make things fair.

so S-T-S is now a must do, and that's bad, i think.
