This is an uphill project. I spent 3 years getting my last car supported in open pilot and it honestly felt like a waste of time when I picked up the keys for a car with less digital hoops to jump through. I plugged and played and immediately had a platform to test on vs a test bench of wires which always had a new error when you powered it up for the first time

We also found a diminishing return the older the car we supported. So now we are currently only focusing up to gen n-1
