5 seats in a car

There are 5 seats in a car. The 3 girls could have sat on the back and Asad, Ayaan in the front. Why didn't they go in the same car. AND WHY O WHY did Ayaan let Asad go alone. At least they could have waited in their own car and drove behind/ahead of him. What is the point of baraat if the groom drives alone?
