Apologies if I've missed previous data on this one - has anyone actually performed a controlled experiment testing the differing drag forces with and without a front license plate? Does a front plate affect the drag enough that your Wh/mi show noticeable increase? Is there any difference between the various front mount options (on nose, on grille below nose, etc.)? I live in MD where front plates are required, but I might be willing to risk a ticket if it makes a big difference in power usage.
