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.

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.

I can't speak for other manufacturers, or even in other countries, but Mitsubishi Canada at least has an opt-out for data collection. You need to call their customer care number and they will remotely disable it.

You absolutely can judge your own behavior when you are impaired

By the time you realized it you were already impaired. That's why professional drivers have a schedule. It's not up to them to decide for themselves that they could go longer.

Fair point.

Sure but if you make that argument, even relatively dumb cars have that as well. At least antilock brakes have been mandatory for a few years (in the US) and traction control might be as well. Both lead to immediate adjustments in driving, more quickly than any human can react.

More automated cars must have some equivalent feedback on balance, sharpness of turns. I don’t know what it is, but they generally execute smooth comfortable turns.

Lidar has strengths that complement where video has weaknesses. That seems like a good thing. However it is bulky and expensive, and not yet produced at scale. Those are bad things. Whether it really makes a difference in simplifying the machine learning, only those developers know. You have to balance the pluses and minuses, and just because one company came up with something different, doesn’t mean it’s wrong.

Maybe it won’t work without lidar but maybe it will - in the meantime Tesla has saved like $1,000/car times however many million they produce. If they succeed, then they have a solid cost and scalability advantage

The deciding point is if someone does develop general self-driving. Will those who are behind be able to swallow their pride and modify their approach?

They don’t though. Waymo runs a few pilots in a few specific geolocked locations with essentially hand built cars at a huge loss. They also have human remote supervisions. They do seem fairly successful and maybe their slow careful rollout will eventually be at scale in the areas that need it most. Hopefully it will work.

While it’s easy to argue Tesla hasn’t had those successes yet, they do have the “at scale” part down and are already profitable on the vehicles. They are close enough to self-driving them at they’re willing to try their own pilots with human intervention. If they succeed, they already have the scaling up done and are profitable on hardware so will quickly surpass other competitors.

I like that different companies are taking different approaches, so we have competition. May the best technology succeed!
