I always found it a bit weird that the Wiimote was heavier on the right than on the left, due to the shape and location of the rumble and batteries. The Wiimote Jackets seem to fix it though, the bulge at the top of the 'mote balances it out and makes an easier grip.

As for realistic resistance...well, that's just something you'll have to get over, I guess. But since you can steer a real steering wheel one and a half rotations each way, and in comparison you can't practically turn the Wiimote over 90 degrees, I don't think people should be looking for realism per say.
