Note: Also posted on Reddit Drove from Cape Cod to Raleigh(600+ miles, overnight) straight thru in my MS60. I've done this trip many times before in my ICE and OMG the Tesla rules on road trips!!! Used AP1 for 99.9% of the trip...sooo game changing on long trips. AP1 Accident prevention: besides keeping straight in the lane, having night vision and keeping a safe buffer between me and the driver in front of me the accident prevention capability was impressive. Case in point: While passing an 18 wheeler(at the point the cab was about even with my rear door and out of my field of vision) I notice my rear, right sensor turning red(truck was turning into me). The Tesla automatically nudged to the left avoiding collision. This all happened in a split second and there was no way I could have reacted this fast to avoid collision. Thanks AP1! Update: on Reddit there was some discussion regarding AP leaning toward trucks. I didn't notice this on the trip down and on the 600mi return trip I specifically looked for this behavior when passing trucks and again didn't notice any lean toward trucks. What I did notice(while drafting an 18 wheeler) is the inability of the truck to stay within it's lane...literally witnessed truck crossing line into passing traffic with many close calls(trucks need AP!). With that said, always be careful and aware when passing trucks even with AP activated.
