There are blind spots on all cars, it's just they are easy to check by moving your head a little, it's the not moving your head that is the problem and relying too much on mirrors. It's a bit different for HGV which have massive full on areas that cannot be seen through any amount of neck stretching, these should be covered by sensors and whatnot. Also people should stay out of both kinds of blind spots anyway, no matter what vehicle you're in.
