I think that by providing an "Alert system" for crossing lanes is only providing long distance reps an excuse for driving without due care and attention. Surely if you get behind the wheel when tired, you should not be using a cars technology to keep you awake when you start drifting lanes! ... A far more useful technology already proven is the automatic breaking when approaching a stationary or slow moving car in front. What is your opinion? Driving without due care and attention (snoozing/whatever) Or having an automatic breaking system that prevents pile ups?
My pet hate is people who can't be bothered to indicate, or indicate incorrectly (especially at roundabouts). Are the rest of us assumed to be psychic?
