Trunk it up!
It is an interesting question though. Hypothetically with just one car someone would be able to leave and come back right? But with the risk of a permaban it may not be worth to test with 2 cars...
Edit: okay we're going Mission:Impossible now... you need 2 cars the same make, model, color, and year. Then when you switch cars you'll also need to swap the license plates without anyone noticing. This is your mission if you choose to accept. This post will self destruct
Edit edit: Don't take any of my advice, and if you do it's only the first one. Trunk life :rock:
