My experience with a road trip rental of a 2020 RAV4 is exactly the same as what you describe.

The ACC was great, and very useful in both high-speed traffic and stop-and-go traffic.

But the lane-center tech was useless, regardless of the road conditions. Even with full sunlight and freshly-painted lines, it didn't work reliably.

When I was test driving a RAV4, the dealer told me not to use the lane-centering when in the slow lane, allegedly because people are coming and going a lot. But it was clear that the real problem was that it would keep you centered even as the line on the right veered off for an exit, which would drive you right into an overpass.

I have a 2014 (so, very old) tesla and the lanekeeping continues to work extremely well. I have literally never had this issue and I live in a rainy area.

"Continues"? Why would it get worse?

So sad that we live in an era of tech where basically everything is expected to severely degrade after 2 years and be essentially unusable after 5.

Roads change over time. The information about those roads gets updated. It continues to be updated well.

What do you mean the information about roads is updated? Does Tesla require info about specific roads?

It can read the street signs, but it also uses published information about the road in the absence of a sign (e.g. you turn on to a new road - what is the speed limit if there is no visible sign?)

that seems awfully dangerous, though? if you drive yourself and have no sign there, you can at least argue. if the published information tesla is using is claiming 100 miles an hour is the limit, the car will speed up?

It uses other information too. It wouldn’t go over 45 or so unless it’s clearly a freeway with a divider and other cars were going that fast. And there is probably something that uses last known speed, and it remembers speeds it has seen before.

But the updates do other things too, like help it understand new kinds of signs or to improve handling of weird situations.

Is this thanks to software updates that Tesla offers? I've asked Toyota and Subaru dealers if they offer OTA updates, and I've been told they don't/won't.

I'd be much more likely to buy a car that has pretty good driver assist tech if it were regularly updated. I don't want to have a car for 10 years if half the driver assist tech is useless when the car is brand new, and it will never be updated.

Tesla software updates are pretty frequent. It looks like almost every two weeks.

I don’t think I’d want software I’m trusting with my life running on a 2 weekly update cadence...
