On one hand there's the sensible-sounding safety-first principle where driver protection is paramount and we must do everything in our power to keep them safe. On the other hand the chances of a freakish accident where a driver is seriously injured or dies because of the lack of a halo-type device is extremely remote, plus the excitement and future of the sport is definitely not enhanced by the addition of such a device. I for one like F1 less because of the halo.
