AhsanAllahu ileikum, my kafir father wanted me to travel with him to another city but I didn’t want, also I fear that I have to pray maghrib in the car sitting (he is against islam) because when we arrive the maghrib time will probably have finished and if it didnt finish I cant tell. Am i sinful?

That's your personal decision.
