I've seen it both ways.

On 330, captains are elected by the whole team. Drivers are chosen by trial. Now, one year, a senior and a freshman were both drivers, one main, one backup. The senior gave up his spot as driver so the freshman could drive after one or two regionals. The freshman went on to drive the remaining three years of his career.

On 1135, it's student-run (and many of the FRC students are seniors), so the captains were kind of automatic. They were also the drive team.

The bottom line is, what works best for YOUR team is what the best solution is.
