The wind turbine reducing the aerodynamics of the vehicle. Now your electric motor is having to put more power out to overcome the greater resistance the air is putting on the vehicle. If you had a wind turbine that captured energy with 100% efficiency and a motor that used that energy with 100% efficiency you would end up with the energy the wind turbine is making being exactly enough to overcome the additional air resistance the wind turbine puts on the vehicle. So at best you end up where you started but since those things can't be 100% efficient you only end up losing energy.
