What do the controls or hill descent do? If you drive a recent model Toyota Landcruiser the new hill descent is pretty wild, a bit like cruise control at low speeds. This is pretty good and allot safer. The hill descent will accelerate and brake for you when you go up hills and down hills, you can control the speed from the dial, no feet needed yes its true watch the video you dont need to use your feet.
The Toyota Landcruiser has some pretty good technology, when in low 4 you drive up the hill and if you stop accelerating the break will automatically come on to stop you rolling backwards it brakes and sometimes stops the vehicle totally and othertimes it let the car go backwards very slowly and in control. This is pretty good and allot safer, watch the video.
