Surprised how much hate there is here for this technology from people who never tried it. I've had one for a year. It is game-changing. You can drive what you like - it supports many different cars.. I can road trip for hours on autopilot and then drive my Subaru on rocky forest roads that would rip the undercarriage out of a Tesla.. It does adaptive cruise control and lane centering for hours on end.. Being able to relax (but monitor) for the 8+ hour drives up and down the state of California is great. Being able to adjust the radio, have a snack, or just sit with your hands in your lap while the car handles lanekeeping feels like a miracle.

There is a 'dating' period when you get it where you and the autopilot learn each others limitations.. Knowing how steep a turn your car can do without hitting torque limits, learning to trust the ACC to slow down with traffic ahead, knowing how long you can sit in stop-and-go traffic without it disengaging (varies based on car and car capabilities), what light conditions it finds challenging (same ones as humans, driving into the sunset) etc. But now I know its limits, know how it notifies when it is reaching limits or unsure, I have full confidence in it when its working within its capabilities.

For those who think this device is going to kill them -- the safeties built in make it virtually impossible. Yes the main device (Eon) runs python code. However there is a hardware device which acts as a firewall between the Eon and the CAN bus which prevents any commands beyond a (very low) torque limit such that the car cannot take any action which a human couldn't notice and correct within 1 second. BY FAR the most dangerous part of my drives continue to be the drivers surrounding me who don't look or signal when entering my lane.

I've been using openpilot for about 6 months and this is exactly how I feel.

Even if it did do something erratic (which it hasn't so far) the torque limit means there's just no way the car's going to do anything so fast and aggressively you couldn't take control.

Investors care more about making money than technology.
