AITA for going exactly the speed limit to save on my insurance?

Tired of Stupid speeders on the roads and road ragers. I bought a new car (2024), and part of the fantastic deal was to install an app that tracks my driving for a better insurance rate. I have a near-perfect score because I don't speed, so I just set the cruise control and go through long roadways. There is a 10 km road I take every morning to work, and the speed limit is 40 Kilometres per hour, so I set the cruise and tune into the morning radio show since it takes a hot minute (about 10-20 minutes) on a two-lane roadway (1 lane of traffic for each direction on a curving road following a river with no way to let people pass safely). I am pissed about getting high-beamed on the entire stretch of roadway, people blaring their horns, tailgating, and just being stupid because they want to speed. I save about 400$ a year on insurance because I take the extra 5 minutes and go the speed limit.

I am never in the "passing" lane on multi-lane roads unless I pass another vehicle and merge back to the right lane. The other day, someone was almost in a head-on collision because they tried to do an illegal overtake on a bending curved road in the early morning with minimal sunlight. Thankfully, the collision was avoided, but the pickup truck about a kilometre down the road pulled up in front of me, got out of their truck and banged on the window, screaming for me to roll it down. I have a dash cam in the front and back of my sedan, so I have the license plate and the guy's face. I did not engage; I just kept looking forward, and when they stepped away, I drove around him while calling the cops and filed a police report.

Your failure to plan correctly does not constitute an emergency on my part. Sometimes, I wish a mental evaluation was needed to get a license because you're driving 2-ton plus machines that have the capacity to merk folks because you can't get your ego in check to "feel" faster. As a young guy in his 20s, I don't get how other young guys behave this way - like, come on, this is why our insurance is so high. Why do road ragers assume I am being a douche for going 40 in a 40? So Reddit AITA for not changing my ways and doing the exact speed limit?

TLDR: don't be a speeding asshole that tailgates folks for doing the speed limit.
