Car and truck are transvehiclist terms. You do not know a vehicle's category until its manual tells you. There are no qualifications to any vehicle category. Any vehicle can literally look any way. Everything from wide tires, long wheelbase, short, and narrow to broad fenders, rugged cladding, tall, powerful engine, and a tailgate. These two examples could be sedans, coupes, club cab, short bed, etc, etc.

Because vehicle desirability tends to happen before you have a chance to know a vehicle's category, saying you prefer cars or trucks or not desiring a certain vehicle category makes assumptions about vehicles' categories, which is wrong and horribly transvehiclist. Say you prefer cars, and you look at a vehicle you believe to be a car on appearance. But then it turns out to be a trans truck... You either have to admit you don't prefer cars or are a transphobe.

Using terms like car or truck perpetuates ideas that we can know a vehicle's category based on appearance alone or that categories have qualifications and common traits to them. These ideas are what keeps trans cars away from car garages and get them sent to vehicle compactors.

I will no longer call my vehicle a car from this point on, and if you care about trans cars I urge you to either ID as panvehicular or even better just dump category designations altogether as well. You only need to tell people, "I drive what I drive."
