If you’re in the right lane, great. If the natural flow of traffic is 15 miles over the limit, any car in the far left lane driving significantly slower than other vehicles invites needless risk. Absolute, inflexible rules frequently lead to disaster. Cars that have to pass on the right creates many disasters.

I am because I am not obtuse and can understand that my style of driving allows for risks. Only use the left lane for overtaking trucks.

That is wonderful. May I thank you in advance for sharing this wisdom with your fellow never-over-the-speed-limit drivers? Empirically, I observe many who may not have heard it.
