FWIW, I put a comma 2 (they've since released comma 3) on my 2020 Forester. I've never driven a Tesla or a Cadillac with Super Cruise, so I can't compare it to them. I have test-driven cars with 'Lane Keep Assist', which ping pongs the car side to side inside of a lane, and tends to have very limiting requirements as far as speed, lane markers, weather, pavement, and so on)
After getting excited about LKA, and then let down by the manufacturers, I researched aftermarket options, and found comma 2. Then I bought a car that was compatible with the comma 2. I hired someone off craigslist to install it, and he was unable to get it to work. So, I returned that car (Carmax - 7 days), and picked another that Comma 2 supported.
The same guy came over and installed it the comma 2 in about 30 minutes, and spent 5 minutes calibrating it and 5 minutes showing me how to use it. It's my favorite thing about my car. I love it. I can't stand driving cars that don't have it. It's like going on a road trip in a car that doesn't have cruise control, or driving somewhere you've never been without a navigation system. It just makes driving sooooo much easier.
I use it the second I back out of my drive way until I pull into a parking lot. A 20 minute drive probably requires 2 to 3 minutes of hands on driving, specifically making turns, changing lanes, entrances, exits, and sharp curves. Anyway, thought I'd share. This technology should be as standard as cruise control. What is the downside to keeping your car centered in your lane, preventing you from drifting, perfectly following the curves, and helping you steer at night, in the rain, when the device can see the lane markers better than you can.
One other note: I think the manufacturers don't provide Comma 2-like specs, because they fear the liability that would come when their independently functioning dealerships' sales associates exaggerate the capabilities to the customer in order to make a sale. They know this would happen frequently, all over the country. Then they envision 5,000 of their vehicles having accidents while their driver's are reading texts. They know this will lead to loss of lives and livelihoods, and will be followed by lawsuits.
Tesla has better control over sales. They don't share these concerns.
