Re: mecanum wheels at 45 degrees

The resultant drivetrain would behave like tank drive, except be harder to build, have low traction, and suffer frictional losses from the mecanum rollers. Not exactly desirable...

Well, if you swapped the rear left and rear right wheels, and then mounted all 4 wheels at 45 degrees, you'd have a rear-wheel-drive front-wheel-steering vehicle (with lots of frictional losses and poor traction).
