sports mode makes the steering firmer, but acutal feed back may not change much.
i also think it's numb at very low speed, ie, less than 10-15 mph. steering and feedback has never been a lexus strength and although lexus has done a fine job on this one, it's not perfect. the lexus power steering is electric which saves gas, but sacrifices feedback. hydraulic systems gives better feedback, but wasts ~ 1mpg of gas mileage.
