This is a company issue, not a union issue as Jon suggests. And since you are not in the union......
This violates a ton of UPS policies. UPS is the only entity that can authorize anyone to use their personal vehicles for delivery purposes. Not the driver.
Secondly, as has been mentioned, you are driving without insurance when you attempt this type of action. Your insurance will not cover you when you are delivering, and since UPS did not authorize your car use, neither will theirs. So any accident you might be involved in will screw you for life. You can also be ticketed if you get pulled over for not having insurance in most states.
Then, add the fact that during this time of the year especially, there are a lot of people watching other people. A car or truck with a lot of packages in it will be interesting enough, considering that there is quite a business stealing packages that have been already delivered, or off docks like Upstate mentioned. People are looking and if they see you, I would suspect someone will call the police. I know I would.
There is no way in hell, if I were you, that I would ever consider using the personal vehicle for delivery, without express permission from UPS management. Period.
