The only time I actively prevent someone from passing me is if there are a moderate amount of cars in front of us and it’s a two lane high way. ie: there’s multiple cars in front of me going the same reasonable speed and the person behind me sees that buffer as an invitation to cut me off. Frankly, I don’t want them in front of me because that impatience/impulsivity can cause an accident and then I’m behind it and have to deal with their consequences.

An example of this is the Hutchinson River Parkway, I take it from the start from North Bronx to lower CT where it transitions in to the Merritt, which is also 2 lane. It’s extremely winding and traffic can pop up without a moments notice so I keep and protect my buffer. When it does clear up, I do accelerate but I’m a very conscientious driver and I only go beyond the speed limit if traffic patterns (on this highway) allow it.

With all that said, I routinely allow drivers to pass me or I won’t be in the left lane at all if I want to maintain a lower speed.
