Not me, but it does look interesting! The big question is if you want to pay $600 for a camera and $400 more or whatever a FlexRay interface costs, with no guarantee that the software can be made to work? There is apparently $1,850 in bounties up to defer the development costs should someone want to take it on:
Depressingly bare BMW porting wiki:
My big concern is the performance of TJA at higher speeds and if Openpilot will have the same issues due to underlying deficiencies in the i3. It has been theorized in forum posts that the reason why it can't deal with sharper bends at highway speeds is that the electronics cannot generate enough force in the steering system. I also suspect that it gets jerky at higher speeds because the ACC/TJA computer is under-sized for processing stereo images at a frame rate suitable for going faster. From a quick browse of the readme on the Openpilot Github page, I'm wondering if the theory about TJA not being able to apply enough force is wrong, and it wasn't an intentional engineering decision required by law to qualify as a level 2 gizmo?
Another concern is if/how their software will function without the factory radar that is common with other marques' ACC implementations but lacking in the i3's setup. They apparently have a way to use aftermarket radar hardware, which might make this project more desirable to those of us who have ACC shut down daily due to sun glare.....
