Small-Scale Question Sunday for February 9, 2025

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

I've never understood the point of cruise control. It doesn't really take any effort to maintain a constant speed.

IMO, it depends on what specific kind of freeway driving you do. My commute spends just twenty minutes each way on a busy freeway, where my speed changes all the time and cruise control is worthless. But I once took a drive through the featureless wastes of rural Ohio on US 30, with hardly any traffic on the road, and being able to rest my foot for two hours on an eleven-hour drive (each way) was nice.

Interesting, I like even plain cruise control. Gets tiresome on my ankle otherwise. But adaptive is a whole nother level. Now you don't have to speed up and slow down as people in front of you do things - you are really just setting a max speed. Super great in stop and go traffic.

I think cruise control is useful for those times where it would take the average driver effort to maintain a constant speed- specifically, avoiding fines when the design speed of the road is sufficiently divorced from its limit (especially if those fines can be levied automatically).

Adaptive cruise control (and the lane-keep assists) is mainly so that you don't crash while you're navigating through your car's shitty infotainment menus, keeps you driving straight when you are flash-blinded by modern headlights, or when you are texting.

I was also sceptical but adaptive cruise control actually makes a pretty big difference for a longer drive.

a) Minimal effort is still nonzero. With cruise control it's zero, and that is nice.

b) Adaptive cruise control is a whole new level. It's amazing in particular during traffic jams when you are going to be stopping and starting a lot.
