It’s so dangerous when the passenger tries to pressure the driver to go. If they thought it was safe they would have gone. If they decide to listen to the passenger instead of their own judgement, they are way more likely to get into an accident. Even if the advice itself is good they might take too long to process it or misunderstand. Like “Take a right, now!” then they drive up onto the curb ten feet before the turn.

Also, if the driver is making mistakes out of nervousness, yelling at them makes it worse every time. My passenger yells anything they can walk the rest of the way.
