Single-player operator interface?

[PneumaticFlea]

My team is interested in a control system that is controlled by a single player. We'd probably still have two joysticks, one for driving and one for everything else. There'd just be one person operating both joysticks. Some people on my team advocate for this approach, but I think it's a terrible idea.

Argument for: Total control of movement and shooting from one person is the most intuitive, as anyone who has played videogames will know. As long as the controls are mapped out efficiently enough, one person can do the job just fine, and without any of the synchronization issues that a two-man driving team can and will end up facing. I know we did a two-man driving team last year, but the controls for this year is a lot more complex and requires a lot more coordination if we were to use two people, and I haven't been on the team long enough to comment on other years, so I think it might be beneficial to try one person control system or at least not be scared of it.

Argument against: As they say, two eyes are better than one. Coordination between driving and shooting isn't incredibly important. If the shooter has control to pivot, they can do their job independent of the driver. In regards to surmounting defenses (particularly opening the sally port, drawbridge, and portcullis), the amount of coordination required to manipulate the arm and control the drive train would be too much for one person to do; two people would have an easier time at it. Additionally, this avoids people having to use their left hand.

So, Chief Delphi Forums. Has any other teams tried this before? Has it been successful? Is it a good idea at all?
