This is not how it works , as others have stated above , you have 1 Normal Button Press 2 Button Touch like a touch screen , just registers that you are touching the button . 3 Button proximity registers if you finger is close to the buttonThis is only used for the thumb and index finger buttons I think , so for instance simply not pressing the index finger button would not show you pointing , you would need to actually point your finger out away from the button . There is a great video I saw somewhere that showed all that , if I find it ill post it . <| sep |> 1 Good chance the truck driver didn ' t even notice . 2 that interchange is fucking awful . I can ' t believe they spent so much money on that highway and you ' re still left to merge in to the left lane . Trying to get a truck which are all stupidly governed to 105 kph to the right lane in heavy traffic is not a fun time !
