Disrespectful or what

So my boyfriend was driving my car. I usually drive but didn’t know where we were going so he offered. Well he revved up my car multiple times. After the first time I told him to stop. He continued to do so and goes it’s a lease it doesn’t matter.... yes it’s a lease that my parents pay for, that is my only car, that if anything breaks due to him being stupid I will have to miss school to sit and get it fixed. I called him out and said how would you feel if I did that to his expensive car, he knows how to take care of his car but disrespects mine. Mind you my car is a tiny suv not any race car/sports car and there was never a need to rev it up sooo much since we were in stop and go traffic. When we stopped I drove from then on but now feel stupid that I can’t trust him to drive my car safely and responsibly. My brother just got his license and knows how to drive safe/take care of a car. Why does my bf not especially when he knows that my parents pay for it (so it’s not even mine)
