It should be my friend, but the transport of the people enjoyed priority.
Now it has grown so big that it is going to be a mammoth task.
If people are in training they cannot earn a salary, but of course a plan can always be made to train unemployed guys as trainers and then to place them in the taxis to do training with the drivers on the job.
Maybe something will come up in the future and in honesty I don't know too much about their inner workings, but I can only comment on what I have seen.

Cheers and thanks!
