I suddenly got very tired today when driving, and noticed my car drifting out of lane as I was unfocused, I was far from home, didn't have any snacks or anything.

Luckily I found a place to park soon after, pulled over, and rested for 20 min or so.

Tiredness can come sudden, it doesn't mean you should loose your license as long as you can deal with it in a safe manner.

For sure, but when you are driving cross-country you sometimes do not have a choice because there is nowhere to stop.

Does it pull the wheel when you're trying to change lanes?

I see the blind spot detection on other people's mirrors when I pass them and that looks cool as fuck but what happens the instant it fails? If I'm reliant on it and it breaks one day am I going to mistakenly merge into another driver's right of way?

If it happens to someone multiple times and they treat lane assist as a crutch then they are not safe to drive on the road.

The best part is they followed up with this gem so I know they didn't pull over like you did:

Call me a Luddite but I won't ride in a "self driving" car. I don't even trust lane assist although I've never had a car with that feature.

I think my sweet spot is 2014 for vehicles. It's about 50/50 with the tracking garbage and the "advanced features" on those models but anything past 2015 seems to be fully fly-by-wire and that doesn't sit right with me.

I'm old though and honestly if I bought a 2014 right now and babied it as my non commuter car I could probably keep it until I should give up my keys. You younger people are going to have to work around all this crap.

That's easier said than done. You can't judge your own behavior when impaired because you are impaired. By the time you are aware you are that tired, you've already been impaired for a long time.

You absolutely can judge your own behavior when you are impaired, I have done that plenty of times and decided that I needed a break when driving plenty of times.

The issue is that you are a worse judge of your own behavior when impaired, so you need to take that into account

My wife had a rental for a trip she and my daughter were going on for a gymnastics event and I got to drive it back from the rental place and it had lane assist.

Every time another car passed in the opposite lane the damn thing would try and jerk in the opposite direction of that car, sometimes almost running itself off the road into the ditch in the process.

I have a Toyota with lane assist and it doesn't. The "lane assist" is part of cruise control. It's off by default.

I love it because it removes a little of the mental load giving me more time to scan the road for potential problems.

Off by default should be the default.

It didn't so much as pull as get stiffer to turn out of the lane. Again, that doesn't happen if your signals are on, so it's a good reminder to use your signals, too.

Like I said, relying on these assists as replacements for proper driving isn't something I would recommend. You should still be shoulder checking and using your mirrors. My wife's vehicle has blind spot detection, which turns on an amber light by the mirror. If you're changing lanes, it's an obvious indicator that it may not be safe. A more thorough shoulder check can identify if the vehicle is actually at risk for collision. For example, if you just passed a vehicle and are pulling away, the detection light may still be on, but you aren't at risk of collision. Alternatively, if I thought the lane was clear and decide to change lanes, the light may be on due to a speeding driver who is approaching to pass me in the adjacent lane. The light will be on even though he isn't in the way yet, and changing lanes could result in an accident. Or maybe someone has been sitting in your blind spot for a few minutes and you decide to change lanes. A quick mirror check indicates you're safe, but that amber light says maybe not. If your shoulder check doesn't catch the problem, you probably haven't done it well enough.

Again, can be good assistance tools, I don't think they're good enough to be replacements yet.

OK yeah, if I have the cruise control on I can see having lane assist. Can you use the CC independently of lane assist?

So it does move the wheel under your hands? That's just gross to me. I guess maybe I should rent a car with it and give it a shot but I don't think I'll like it.

When cruise control is on, yes, but it's extremely gentle. The slightest bit of resistance from the driver will overpower it.

woah, that's pretty cool actually.

The amber light in the mirror is what I've seen in other people's blind spot assistance. It's really cool but I'd hate to get used to it and depend on it the day it stops working.

If we lived in any sort of reasonable or responsible world then these cars would be banned from public roads all over the globe.
