How does the collision warning cause crashes? It's nothing but a visible warning in both the HUD and between the meters on your dash.. Only if you are going to rely solely on that 'red car' image, then yes, you might get a crash but normally I doubt you would only look there before you actually break. But is this actually a part of the package? I thought it was more of a standard feature?
The blind spot indicator is easy to see when you look into the mirror, but also to feel through your steering wheel. I think it is a great improvement since I do a lot of city and traffic driving and very often there is someone in my blind spot and then I either know it from the vibrations or from the visible triangle in the mirror
