I know Elon has talked a bit in the past about autonomous cars, and as I recall, he's mentioned the 2018 timeframe. Now that BMW has planted a stake in year 2021 for autonomous, I hope Tesla comes out with a more definitive date for their autonomous system. I, Robot car: BMW to launch autonomous electric flagship in 2021 - Roadshow Ideally I'd like to hear that the M3 will come with the hardware for autonomous level 4, but I suspect the software and laws may need additional time. If the initial M3s ship with the needed hardware, I will likely outright buy the M3. If autonomous driving is missing from the initial launch of the M3, I'll probably lease for 3 years and by the time the lease is up autonomous should be either out or much closer to reality. I saw in the MS forum that there's likely AP v.Next coming to the MS sometime this year due to leaked schematics. I'm by no means an autonomous expert, but my gut tells me even those AP enhancements aren't yet up to the level needed for full autonomy. I would think more cameras and sensors are needed for full level 4.
