As a retired police officer, all the comments about not drawing attention to oneself by doing stupid things are right on target. Most of us didn't really care about minor equipment violations---unless the person gave us a "reason to care." Additionally, equipment regulations vary from state to state. In Oregon, there is no regulation requiring bumpers. Check state regs, usually on-line, if you are really curious. And, if your state requires a front number plate, please display one. It will eliminate one reason to stop you. If you have the required plate, the lack of a bumper if required won't likely be an issue. And besides, there is new technology out there that uses equipment in police cars to scan plates coming and going. If your MG is stolen, and has a front plate, the chances of recovering it are greatly improved. There are a lot of really dangerous "fast and furious" out there to deal with, not British sports car nuts. After all, we are essentially harmless, right?
