Looking for any perspectives on "autopilot" / lanekeeping/ adaptive cruise functionality in Tesla competitors. I test-drove a Model S today with autopilot and absolutely loved the car, and in particular the autopilot feature. The car and autopilot exceeded very high expectations. That said, unfortunately I need to consider non-electric competitors due to my driving profile and very long length of typical commute. That same long commute makes the autopilot functions also very desirable, and dare I say "necessary", especially after experiencing Tesla. I'm leaning heavily toward the Tesla, but want to make sure that I'm not missing anything non-electric that may be available with advanced lanekeeping and adaptive cruise functions. From what I can tell, the Tesla does a much better job than anything I've found in research. My main priorities are autonomous "middle of the lane" keeping, including around gradual curves, and auto braking/accelerating in stop and go traffic. Does anything else on the market come close? Anything rumored to arrive in the next few months?
