I'm a first timer and have a used(1 yr old) ES300 and am having difficulty getting used to the accelerator. After 30 minutes or so of driving with soft soled shoes it makes my foot hurt. Seems like there is a lot of resistence in the pedal? I realize that this is an electronic throttle and have looked at the pedal assembly and it appears to have two good sized springs (one black and one gold) that provide the return pressure on the pedal. This is driving me nuts. The dealer humors me, but says everything is OK. Maybe Lexus owners don't wear soft shoes?
