>> Lane assist is enough for me. Does lane assist work at night when its raining or snowing ? I dont think I have ever needed lane assist during daytime however I find driving at night in snow or rain to be very stressful.

Adaptive cruise control + lane assist can keep the car in your lane at highway speeds without input in specifically clear weather and well-marked roads and as long as the road doesn't curve too much. Lane assist doesn't work when the lane markers are obscured, so it fails specifically during the times you find lane keeping stressful.

  Why does it seem like the functional effect of these systems is to serve as "mistake multipliers"?

    Having just driven a brand new VW Passat that had a lane "assist" keeping that tried to jerk the wheel without so much as a beep multiple times, this sounds like the perfect way to describe it.

Lane assist during a snow storm would be a game changer. The number of times you end up driving in poor conditions in the northland is a pain. The 2008 Kia Rio had the best window for driving in snow. The A-frame window that looked directly at the center line was brilliant.

  Maybe. When driving in snow there are other considerations besides following the lanes buried somewhere beneath the snow. Like "has this lane been plowed" ? And "has the plow actually followed the lane or gone in the middle of the lanes" .

    There are certain roads where I live that are normally two lanes in each direction, but in the winter there's not enough traffic to need two lanes. When they are heavily snow covered, they become one lane in each direction, straddling the painted lines. This is unofficial and probably illegal, but clearly safer, especially when snow from the plows starts piling up in the outer lanes. I wonder what self driving cars will make of situations like this?

Tesla M3 lane assist works well at high speeds with heavy rain (dark conditions but not night iirc). It felt like it was better in recognising the lanes than me, maybe because the front camera is mounted higher than my eyes :D

  Given that I mainly drive in the city I don't care much about lane detection but I do care about automatic break system and similar. Some which supposedly Tesla had the best of. Until people ran tests on it and realized it's much worse then some much less hi-tech solutions. (And it wasn't just one group which ran similar tests and came to the same result). So I'm always very careful when Tesla (or other Car manufacturers) promise that "their tech works the best"/"very good" until I have seen some reasonable independent tests.

I find lane assist and adaptive cruise control incredibly nice if you frequently have two hour driving trips on the interstate. I can focus on watching the environment and cars around me, rather than spending a lot of effort on lane-keeping and making sure I'm not going faster than the car in front of me. Sure, it doesn't work in heavy snow, but I also wouldn't trust it in heavy snow either. I appreciate that my car doesn't provide false confidence in dangerous conditions. My other vehicle lacks any of the modern radar features, and the one time I did the same drive with that car was... surprisingly more stressful.

  A requirement for my next car is also having a "traffic jam" mode. Lots of adaptive cruise control systems only work over a certain speed. I live in a traffic jam prone area, and being able to not worry about stop and go traffic takes all the stress out of driving.

    My Kia will follow the car ahead of it down to a complete stop and resume when the car ahead of it moves, I believe. Though I rarely enable it anywhere but the highway. (Kia understates the capabilities of their ADAS a lot, probably so people don't abuse it, but it will pretty much drive itself as long as your hands rest on the wheel.)

Back before GPS became common, I had an idea for a navigation aid that would also be useful for things like lane assist and would not be affected much by weather. I have no idea if this would be feasible. The idea is that when paving a road, mix a whole lot of passive RFID tags into the paving material. By a whole lot, I mean that every square meter of road should have a dozen or two tags. The tag IDs do not have to recorded in advance, and there is no need for any systematic ID assignment. Just order a bazillion tags with random IDs and dump 'em into the road. Then afterwards you send vehicles over the road that have readers than can gather data to make a database of what tags are in what lanes of what roads, and where. The where part just needs to be the distance along the road from some reference point. That data gathering can be done by paying commercial vehicles to install and use the readers. The idea was to then make the data available to the general public. You could then make car navigation systems (remember, this was pre-GPS) that could read the tags in the road, consult the database, and figure out that they are on road X and they are Y meters from the reference point of that road. You could also continue to pay commercial vehicles to gather and report data. By comparing that data with previous data, you might be able to detect damage to the road. For example, if a pothole develops, that should lead to a loss of some tags, which should show up in the data.

  I like the ingenuity of your idea here - my only thought was if RFID readers could detect/register tag information quickly enough to make this work. You could generalize your idea to a more normal case of 'mix balls of {METAL/MATERIAL} into pavement and equip cars with sensors' Clever.

I wouldn’t trust any driving automation to handle a situation that I couldn’t handle manually, especially if it relies only on sensors equivalent to what I see. These automations are extremely useful to relieve long and easy drives. Not to handle difficult conditions better than a concentrated driver.
