[Help Request] Can not find lane_position from observations

I want to use the lane_position information for RL training. But, even if I have set the lane_position=True, explicitly, I still not get the lane_postion from the env output variables.

Hello @JiyuanTHU, apologies for this oversight, the formatted observations do not yet contain lane position. You can still still currently get that information from the unformatted observations that are included in info:

info[AGENT_ID].env_obs.ego_vehicle_state.lane_position

#2143 fixes this.
