Do you think my nephew deserves this?

I'm 30, and I live with my mom. Reason being is irrelevant. My nephew who's 19, and his girlfriend who is 18 moved in a few weeks ago. I have a car that stopped running about a week ago, and my mom is letting me borrow one of her cars while I save up to get my car fixed. It needs a new transmission. My nephew, and his girlfriend share the same cat. It's not running right, and its leaking oil. My nephew is currently unemployed, but his girlfriend works so my mom said he could use her car (the one I use) so long as he only uses it to take his girlfriend to, and from work. Well, he took the truck this morning. I assumed he took his girlfriend to work, but after he was gone for two hours, my mom was suspicious. She asked me to take the truck, and go to the store to get some things for her. The truck was gone, so I told her the truck is gone. She texted my nephew asking where he was. He said that he went to the post office, and stopped off to hang out with a friend, and he totally forgot about the truck. My mom was pissed. She texted him saying "come home now..." my mom was leaving when he got home. She stared at him, and was like "I'm not happy with you at all. Get your ass out of that car, and in to the house. At least that's what my nephew said she said. I had a small talk with my nephew, and told him that he did screw up. He said "I know, what I did was fucking stupid" then I told him that "but you live and you learn. Consider this a lesson". Then he was like "oh I will, I'm never driving that truck again. Your mom terrified me". Anyways, I feel really bad for him, because without that truck, him, and his girlfriend are going to be in a very difficult situation. My mom just had me take the truck to the store to get some stuff, and I know he heard me get in the truck, and drive away. I'm afraid he thought that I was just taunting him, or something. What do you think? Does he deserve the way he's being treated?
