> GPS also often gets confused and suddenly thinks the car is on a frontage road instead of the freeway. When driving on Highway 17 (between Los Gatos and Santa Cruz, southern silicon valley area), very often my GPS will suddenly jump to being in one of the tiny mountain roads that parallel 17 and trying to start rerouting me back to 17 even though I'm on 17. For anyone familiar with 17, you can imagine the consequences if the car braked hard in the middle of a corner from highway speed to tiny backroad speed!
