Thank you Jakob! The code is working now.
But unfortunately the vehicle speed and position I'm getting at each step
is the ego vehicle's speed and position were I wanted to retrieve the speed
and position of the vehicles around my ego vehicle.
Could you help me with this. Thanks in advance!
Regards,
Surya Soman
