You are. The vehicle isn't your property. The vehicle is the only property you have a say about. THat's it.
And that's what it comes down to, you feel that you are entitled to lie to a property owner and violate his rights, and that your lie is constitutionally protected by the same right that you wish to violate.
The hypocrisy of your argument is beyond belief.
You want to claim property rights to the inside of your car, while denying the property rights of the other individual while you are inside his property boundaries.
Unbelievable hypocrisy.
