Valets back in because their customers don't care how long it takes them to park the car. They've already gone inside and are about their business. They only care how long it takes the valet to retrieve the car. Their tips depend on retrieving cars quickly. They also have captive lots no one else is driving in, and a system for navigating them that the other valets understand, removing ALL the other complicating factors that cause people to think it might be safer to head in. You can't extrapolate from their situation to everyone's just because they "park cars all day."
