The activation of autopilot features should be pretty straightforward on your car since the hardware is already installed. It should be a simple software upgrade. Is it worth the price? I would say yes if you do a reasonable amount of highway driving. My 70D came with autopilot prepaid, so I have the adaptive cruise control features right now and Elon Musk has said the lane-keeping features should be out at the end of this month. During the first 4 driving days after my purchase, I covered over 2,000 miles and never felt the fatigue I typically feel with other cars on long trips. Part of the answer is the great handling of the car, part is the comfort of the 2nd gen seats, part is the low noise level, but a big part is the reduction in effort cause by adaptive cruise control and auto-dimming headlights. Even when traffic was relatively heavy I left the cruise control on and it made the driving experience so much easier than it would have been otherwise.
