In Oment veins, how to get speed of a vehicle by providing vehicle ID which is not transmitting or receiving any message?

Question

I want to to get vehicle speed by defining a function like getSpeedById(Std::string vid) which will give me the current speed of that vehicle. it doesnot matter the vehicle is receiving/transmitting any message. I am using TraciDemo11p example file. In that example, i know that I can get current speed only when the message is sent/ received. But I want to get speed of a particular vehicle all the simulation time which will not transmit any signal at all.

See answer https://stackoverflow.com/a/49973662/4707703 for how to iterate over all currently simulated vehicles in OMNeT++ and how to get a pointer to their mobility simulation module. From there, it should be as easy as calling getCurrentSpeed (instead of getCurrentPosition, which is done in the linked answer)
