Wheel motors can work; there are certainly enough real-world examples, 
ranging from bicycles and scooters, to railroad locomotives and large 
earth-moving equipment.


But they make hard engineering problems even harder; and that adds cost. 
They add weight, which worsens ride and handling.


On the flip side, wheel motors are popular gimmick to add a 
"revolutionary breakthrough" flavor to lure investors into shady 
outfits. They're right in there with magic batteries and impossible 
range claims.


Only time will tell...

The Mitsubishi Imiev prototype had hub motors.  You may have noticed that 
the production model didn't.  I don't think that was entirely a cost-driven 
decision.

The original GM Impact was a 2-motor design (though not hub motors) and it 
also dropped to a single motor when it came time to make it a production 
vehicle.
