You may have different comfort zones and styles for driving.
Your spouse may drive too fast, too slow, too cautious, too reckless. They may drive too closely to the car ahead. Or switch lanes too often, or not enough. You may even have different routes to get to the same place – some like scenic routes, some like fastest routes, some will go out of the way to avoid traffic.

Unless your spouse has a proven track record of reckless and bad driving, trust that their driving will get you to your destination.

Have confidence in your spouse. They are doing it their way. You have the same goal – they also want to get to the destination in one piece.
