2) It is true that there are an abundance of gearing options including two speed gearboxes (which make no sense on a mecanum drive). The limiting of voltage is only used in this example when high speed maneuvers could be dangerous or strategically bad, like knocking over scored game pieces. I agree that it would be silly to limit voltage without the option of using 100% power, but that is not what we are talking about here.
To address 1) Top speed, by itself, means very little in the context of playing a game. Time-to-target does. 610 epitomized this in 2013 with a 6-CIM drive with a top speed of something around 10-11fps. They 'quickly left behind' many teams geared for a higher top speed.

2) Like Ether said, this is exactly what we are talking about.

Having said that, 95 is experimenting with mecanum wheels and using the joystick throttle to change the joystick's input scaling in order to slow down the drive-train when desired. However, our intention is FAR different from that of the average team who builds a drivetrain and goes "oops, too fast and twitchy to control, better cut down motor output!"
