Hey!

We don't train in simulation (if you are talking about ML training). Our ML training is done purely using real world data.

The simulator is to allow developers to "test drive" our autonomy core and API for free.

We have real vehicles as well, but you can imagine it's more expensive, time consuming, and generally slower to let people test on real hardware. Hence, if people like what they see in sim, they can get in touch with us to deploy their code to real machines on a case-by-case basis.
