First potential hitch. How do you file legal paperwork in the name of someone who is dead? Do you have ID to prove who you are? While you can probably file a court case without photo ID, you can't file anonymously in most jurisdictions. And you can't use a fraudulent identity like the name of some dead person...
Trust me. Things will start moving very quickly.
Exceed the speed limit. Reject the fine claiming you are dead.
Trust me. The possibilities are endless and take my word, I would enjoy them.
Yes, I am not a lawyer. Never claimed to be one. I have worked with law in two jurisdictions, incl. US. The fields were:
1. Patent law (I am not a patent lawyer either)
2. Regulatory (speak FDA)
While you can screw up, law is not that difficult. It is even easier in countries with codified law.
What's worse you have no rights because dead people have very limited rights.
This is still the west and courts still work. Don't be intimidated.
