    Feb 2020 paper issue of Car and Driver mag has story on Comma.ai aftermarket Self Driving system for "most Toyota and Honda" cars, which I'll assume includes Primes with elec steering and other elec braking features.

    Says its about equal, more or less, to Cadillac and Tesla factory systems.

    I'm about 85% happy with Prime's radar Cruise Control, and IMO its the biggest improvement in cars since automatic transmission. To me, a decent Self Driving (steering added basically) would be perfect for my daily long freeway commute, some in very slow traffic. Any other aftermarket add-on Self Driving systems?

    Anyone with exp with Comma? I tend to be a late, rather than "early adopter", but this sounds like just what my Prime and my commute is missing. Only got 4K on the car so far, maybe I'll wait for a few months or when I'm at 26K with only 10K full electronics Warranty left, to hedge my bets.

    2020 Prime not yet included, but 2019 is, so I guess I'll need to wait because I'm not up for "manually adding support" (whatever that means) with its Open Source software.

    comma two devkit | comma.ai shop Only things I don't like is screen wants to mount in center of windshield (Caddy and Tesla mount on dash), and I rather not the "face monitoring" feature. Maybe point that camera at a bug-eye face mask, lol.

    C & D story says Toyota says "will void warranty", but I'm not too worried for few reasons. Mainly, IIRC from Business Law 101, sellers need an honest to goodness Cause and Effect reason to Void Warranty in most cases, and/or can only Void Warranty to the extent bringing it back to specs is not covered. Like maybe Toyota could charge for resetting System Software to factory, but unless they can say using Comma actually burned circuits Warranty would be upheld in court. Then again, putting car under completely new system hardly trivial, and Toyota would probably send their "A-team" to any court test case.

    See this thread: My Prius Prime Drives Itself | PriusChat

    Though I still take serious issue with any true "self driving" claims at this time. The design, testing, and certification of systems reliable enough for general consumer use just aren't here yet. Misuse of existing driver assist features has already led to self fatalities. If or when such misuse leads to collateral fatalities, on systems not already demonstrated or certified as safer then average human drivers (about 1 death per 100,000,000 vehicle miles traveled), the misusers should face full liability, potentially even vehicular homicide charges.

    Thx for link. Consensus seems to be "works great" (for intended use, staying in one lane on freeway). Toyota's "lane keeper assist" works, but will want to bounce you from white line to white line.

    When you add in less fatalities because these cool features make it more attractive to buy new cars in the first place (which are safer for other drivers for all sorts of reasons) I'm sure that even with lots of misuse we still come out way ahead, and any deaths from early adopters helping makers "figure it out" wont even be a blip on the radar. Five years ago I was convinced all this "self driving" was simply not gonna happen anytime soon, because the public would force politicians freak out for all sorts of reasons. Looks like I might be wrong.

    I'm sure old skool 1960s Cruise Control caused its share, and still does. Heck, things like power steering, A/T etc that enable the elderly to keep driving huge cars is an issue, as reflected in higher insurance rates.

    I plan on getting this after 2020 Prius becomes "supported" and a few others test it.

    I don't share that confidence. You must compare against equivalent new cars without those assist features too, or with such features turned off.

    Full
    self-driving is a really tough analytical and computational problem, far beyond what we are accustomed to seeing in other applications.

    This system has only two cameras.

    Tesla has eight cameras (covering a complete 360° around the car), one forward-facing radar, and twelve sonars (also covering a complete 360°) according to Wikipedia. The computing platform is also far more sophisticated.

    2020 Prime is supported. I'm using the first gen on my limited and it works great. The comma 2 has an IR camera so it can see you in the dark and a better cooling fan.

    I thoroughly enjoy my comma setup. But IMO, its a stretch to compare it to Tesla. Comma is LKAS + ACC on steroids.

    I've got a 2020 Prime and a Comma 1, and it works really well. However, I'm running a slightly modified fork to give smoother steering. The 2019 and 2020 Primes have TSS-1 like the older 2018 and 2017, but they have an upgraded steering sensor. The better steering sensor is important to prevent ping-pong effects (where the car overcompensates back and forth due to poor precision or feedback delay).

    The main OpenPilot code doesn't take advantage of the upgraded steering sensor, but several forks do. Hopefully, Comma.ai will accept the pull request to incorporate the new sensor so 2019 and 2020 prime owners won't have to run a fork to get smoother steering.

    What's a "fork" in this context?

    Forked or diverging software paths?

    A "fork" is terminology used in some source control software, like Git. OpenPilot is open source software hosted on GitHub, so anyone can easily copy the code and publish their own version with minor or major tweaks. The code has diverged from the original, so it has become a fork.

    GitHub, and the underlying source control software git, makes it easy to merge new changes back in, so it's pretty easy to make a fork with your specific code changes, yet always keep it updated with the original software so you continue to get updates and improvements.

    I have the Comma 2 on my 2018 Prius Prime Advanced and it gives me 98% of what I want. New option called the Smart DSU will be released soon to make it even more desirable.

    Took me 20 minutes to install.

    Very Little Ping Ponging between the lines.
