motorsport infobox ok i agree with what you are saying if the information is available then it should be added however when i went to add the template to british formula one series i couldn't find any data about any teams in the series i know which drivers ran which cars but not the teams that were running them i suppose i could add a question mark or something like that for those fields i can add constructor and engine info but i'm not sure how relevant it is being as most of the cars were second hand i realise making the change to the template was a bit bold on my part without considering why those fields might have been left you are welcome to revert the changes back
