Wow. I can't say I blame you, glad you exercised restraint. I've heard of cases like this (folks getting in the wrong car). In the late 70s my mom went to a car just like hers, and her door key unlocked the door, but the ignition key wouldn't turn. She looked around the car and only then realized she was in the in someone else's vehicle.
Re: your very temporary passenger today - something tells me he'll never do that again.
Edited to add: Thank you for not handcuffing him and holding him at gunpoint untill LEO showed up.
