Tesla's EAP is a great driver assist tool. Now that I've learned that just a slight resistance against the steering that AP is doing is enough to satisfy the system that I am engaged, I can make my whole 33 mile commute "nag-free." Still learning more about how to use it... Just learned today how to successfully enter the HOV lane where it begins. Makes the commute much more relaxing, in stop-and-go traffic, and just cruising. I get frustrated with people who complain because they don't understand it, or just haven't used it. It is NOT SELF DRIVING, it's more like a "Co-Pilot", and when used correctly, it's safer than non-Auto-Pilot travel.
No problems, love it.
