Question, does going slower save gas? If so then there is a reason other than weather to go slow, also in towns with barely any sidewalks, drivers need to go slow to avoid pedestrians and bike riders
This is solved by being aware and being mindful. Scanning the road ahead at all times. Simply driving under the speed limit in case you may need to avoid something is basically being willfully blind until something is right in front of you, AND being disrespectful of everyone else on the road who a) is driving the speed limit and b) is paying attention. Speed limits are in theory calculated based on where you're driving. Residential speed limits are that way because it's determined that's the fastest maintainable speed you can hold while still having adequate time to react to things around you. Commercial street speed limits are likewise calculated the same. If someone on a bike is cutting across 4 lanes of traffic, that is their bad, the normal conditions do not predict that kind of behavior. We have crosswalks and stop lights for them.
Driving under the posted speed limit is like waiting at a stop sign 3x as long as you need to, just to be EXTRA sure nothing is coming, despite the fact you can clearly see
nothing is coming. That is nervous driving, not prudence. Prudence is driving the posted speed limit and staying aware of your surroundings at all times.
I think the reality is that, as a country that drives everywhere, we like to put our brains on autopilot when we get in our cars, especially for daily routines like going to work and coming home. We naturally drive a speed that our brains feel equipped to handle, that is completely divorced from the actual speed limit. That is what happens when you're not being mindful when you drive: automatic processes take over.
It makes me wish for the fully automated driving of the future. I used to rebel against the idea of giving up control behind the wheel. But when so many motherfuckers drive "their style" instead of the actual way you're supposed to drive, fuck it. Let's absolve anyone of having to do any real thinking or pay attention behind the wheel, as long as everyone ends up driving the same way. I'm just so sick of that one special snowflake, whether they're distracted driving or WORSE, a frightened driver, completely jamming up the works and then belligerently telling others its their right to fuck up everyone's commute. It's enough to make a body say "if you're that scared of driving then take the bus. Otherwise L2DRIVE."
