I am speechless. I just drove 1500 miles from Minnesota to Florida with my comma 3. It felt like I had entered a cheat code into the simulation. I drove alongside thousands of other cars that probably had no idea this option was available to them. Well done, @comma_ai

I have a comma three and it is great. If you can’t (or won’t) own a Tesla but you own one of the comma-compatible cars, I HIGHLY recommend it. Self-driving functionality on a budget.

Using @comma_ai for long-hauls. This thing drove me from Prague to Belgrade and back without issues. It can keep you in lanes almost all the time, change lanes, adapt the speed, stop & go in the traffic. It runs opensource openpilot which gets better every month.

@comma_ai I can honestly say the C3 is the single best purchase I’ve ever made. I can’t imagine driving without it now

@the_blueprint @Ebony84Rose Openpilot is better and far cheaper. Plus it works in way more cars. Assisted driving, for those of us that have used it, is much more relaxing. Especially on long drives over 3-4 hours. I love driving. But I feel more alert and rested when using assisted driving on long hauls.

The most impactful thing to come out of AI for me is not ChatGPT. It's another little-known product that I've been using for a year and a half now. (They do no marketing whatsoever) It's @comma_ai and if it supports your car, buy it. It is well worth it.

@comma_ai I've been using openpilot for about 3 months now. Probably one of the best purchase decisions I've ever made. Great work @comma_ai team and @realGeorgeHotz

@comma_ai I have logged 3,780 miles with Openpilot engaged. Since I've had a Comma Two installed in my car, I have driven about 3,982 miles. This means my Openpilot engagement rate is 94.9% Now if we go by total miles driven since OWNING the car, the rate is (3780/5800 miles) = 65%

drove 2+ hrs with @comma_ai Comma 2 w/OpenPilot in our 2017 Subaru Impreza. Fascinating that a team of ~12 is able leverage available sensor suite that comes with almost any modern(2016+) car and make it better than the stock driver assist using a 2016 cellphone (LeEco LePro 3).
