Hi, hope you are doing well!

I use SimControl and I am curious about why you want to reset localization when restarting SimControl.

Currently, if you pause SimControl and restart it, it will just continue from where it left off. Are you proposing, in the same use case described above, it should reset the vehicle to the initial dummy position map_service_->GetStartPoint(&start_point)?

By default, you are able to jump to any starting point for different scenarios. Anyone may shuttle down SimControl by mistake, and this functionality not works any more even restart the SimControl
