Also, all the guys that drove too fast in safety car conditions get a 5 sec penalty. That doesn't feel right, as they're breaking a safety rule, rather than just a sporting code (like weaving, or passing the safety car).
Maybe there were too many to punish properly, which would've have been 24 seconds (equivalent to a drive through). It does set a precendent maybe and means that it may become a tactical penalty, the gain being greater than the punishment, which is bad for sport.
