I totally agree with you... but I disagree that the car should be the enforcer of this behavior (unless there is actual danger of hitting a barrier, other car, etc). Drivers should not have an adversarial relationship with their cars. On a winding two lane (same direction) mountain road with light snow and no traffic, it's silly to tell the car 'I am going to cross this stripe now' to avoid the car trying to steer me into the barrier. I am constantly driving on top of the lane lines to avoid snow, ice, minimize breaking, and generally drive smoothly so as not to put unneeded forces on a car in icy conditions. Edge case? Yes, but there are tons of them. Examples (imagine snowy conditions at night): https://goo.gl/maps/bs6wRGZNywz39RgD8 https://goo.gl/maps/bs6wRGZNywz39RgD8 https://goo.gl/maps/XHHkGx9xtg8y9UWt6 https://goo.gl/maps/XHHkGx9xtg8y9UWt6
