The reason for dawn start: It helps mafia out because they know there partners and they can look who they cant kill to know who sniper is, so they dont have to use a spy code. it helps town out as well since there is a ml, even if sniper does end up shooting d1
Daystart is just as good for town, and I guess I can see why you'd give the spy the added knowledge of knowing the driver so he can confidently whisper the sniper his team. Hmmm. It might work. Worth a try anyway.
