i believe that in many instances the people who are extremely into video games do general make good drivers because it gives them experience; yet don’t count out those less into them because you might miss a very good driver if you do.
Because of this I think in this question the real question should be what makes a good driver; not just who makes a good driver. Some of these things would be things such as reflexes, the ability to make a quick but accurate judgment, skill at the controls, the ability to work with others, and ability to plan ahead would be just a few among the many qualities that would make up good drivers. The list can truly go on and on. As for methods to prepare them for competition, there are plenty to chose from.
One of the easiest methods to train them is obviously to either use your robot or use a robot from another year equipped with the new wheels and actually use it to train your drivers to how the conditions will be. even if the two robots are not exactly alike they can still give the drivers a general idea of what they are facing.
As for using video games to train the drivers is a good way; however the way you train them with the games can vary. With people not that experienced in video games it may be a good idea to go all the way though the games simply so they can get good at using controllers and really get used to them.
However for people who have allot of practice with video games, simply going all the way through them in the normal way will be no where near as effective given the fact that they all ready probably have years of experience with them so a few weeks playing them will not do much to help them. With those people you need to fine tune their skills.
one of my favorite ways to train them is to do stuff such as having the drivers in a different room then the game, then playing the game through until you reach an extremely difficult situation. then you can pause the game, power off the tv, and then bring the driver into the room. You give them the controller and unpause the game at the same time as you turn on the tv. That way the driver has no idea what they are about to encounter and will force them to work on their reflexes and quick thinking to safely get out of the spot. For added difficulty you can switch the games on them.
That is only one method to train them however if you get creative you can come up with other ways to train their skills.
Also remember the fact you get 2 drivers in the game. That is also going to determine training methods because one driver you are going to want to train more heavily in driving skills while the other one you will probably want to train more heavily on judgement and shooting skills so they can accurately score on the opponents.
Also because of this fact the drivers also need to be able to work together effectively and be able to know what the other will most likely do in the competition. Its no good having a great shooter if your driver makes sudden changes and the shooter cant anticipate it.
Also the major thing you have to prepare the drivers for is the rules so make sure they understand them before you let them drive. penaltys can make a major difference in a close match so it is no good if you lose a match simply because you get a penalty.
