At $2500 per year, I would expect that this would cost on average $100 per trip when actually usable. Maybe more.
If you live somewhere where you only experience highway congestion 25 times a year, you probably aren't the target market.
I wonder if it drops down into a less-capable driver-assist mode when the speed goes higher, such that you can still just monitor the system for nearly all of your trip. Or does it drop you out into full human-driving mode?
My car with radar cruise and camera based lane centering: can go any speed, doesn't need a leader, handles terrible conditions (notably it sees better than I can during night time rain with glare from on-coming traffic), comes to a stop, starts from a stop, and handles some pretty crappy lane markings.
It don't handle sharp corners and doesn't auto-drive. It does, however, take 90% of the effort out of the place I spend most of my driving time - highways.
Putting lives at risk with a "beta" self-driving vehicle is insane.
So if you like driving, then you might choose to live somewhere that's a "longer commute" even though you needn't - as this is part of your day which you enjoy. Now, that's probably not going to be bumper-to-bumper freeway traffic, but it absolutely might include country roads at limited speed - I said enjoys driving not racing, if you like track racing and have $$$ you can indulge that without owning a road car at all.
The car handles speeding up and slowing down for me based on what the car in front is doing. I just have to steer. I know that jumping lanes is not going to get me there much sooner but it's hard to resist "competing" to get there first.
