I’m a female (obviously) and have named two of my cars: the first, a Neon, Ignignokt (after the ATHF character) and the second, an Altima, Naobi. I loved my second car dearly, but she was killed in an accident (not my fault!) only a month after her purchase. Since then, I haven’t named my Subaru wagon (though I’m convinced it’s male).
I think naming cars is a way to build comradery with an inanimate object- in hopes of building a mutually beneficial relationship. In my case, it’s only served to bring heartache 
But if it makes you feel safer, or take more responsibility- why not?
Peace, and don’t drive like either of my brothers.
