Assertions about safety are irrelevant. This is not what this law is addressing. Furthermore anyone who has used even automatic lane tracking knows their concentration falls off rapidly when they aren't actually driving so a "safety" driver is a misnomer since it's likely in the event of an accident they won't realize in time. You're just adding another victim if there is an accident at all.
