>For a regular motorist who isn't planning on attacking the police officer, putting your hands on the steering wheel does nothing to effect the officer's safety.
It very much does. Cops are humans if they see you know how to behave instead of making there job harder they will notice and appreciate that.
>Furthermore they're also generally pointing a bright spot light directly at you, destroying your awareness and ruining your judgement, so it's reasonable to expect that orders are going to be followed sluggishly and imperfectly)
Only if it's too dark to see, so once again help them to help yourself and turn on the light inside the car. If these simple instructions are too hard to follow you shouldn't be driving in the first place.
