I think a lot of people should prepare for some disappointment, because my prediction is fairly pessimistic.
How many Model S owners drive with the Lane Departure Warning feature turned on? I do, but I think I'm in the minority. I think most owners turn it off because it issues a lot of false alarms. This morning, I had it shake the wheel for me because it got fooled by a
shadow on the road.
I believe the future Lane Keeping feature of the AutoPilot suite is based on the same sensor input as the Lane Departure Warning. If this is the case, then it's well away from being ready. Right now, if you engaged it with the current software processing that's doing Lane Departure Warning, your Model S wouldn't last 15 minutes before it steered into a concrete barrier.
Here are my predictions/speculation:
- I think we'll see self-parking features rolled out well before lane keeping.
- Self-parking might be ready by the end of the summer.
- Model X will be released later this year, and it won't have lane keeping either.
- Lane keeping implementation in existing Model S cars may require hardware retrofit -- either additional sensors, a faster CPU, or possibly both.
- Lane keeping in existing Model S cars won't be deployed until Q2 2016.
The existing sensor suite is the bare minimum required to do lane keeping, and it's going to require extraordinarily sophisticated processing to do it, including camera & sonar input, and even input from the radar tracking things like the lane markers (reflectors/bumps) and side barriers. The on-board CPU for the tech features is already heavily taxed (watch the update rate/frame rate of your kW meter get halved when you engage navigation), and doing this kind of background processing for lane keeping might be more than the existing CPU can deliver.
Sorry to be so pessimistic, but I think there are major obstacles to overcome that haven't yet been solved.
