I've also owned mine for nearly four years, and am eager to replace it. Primary reasons are a rough noisy ride with a few buzzes and rattles, cheap interior, no 360-degree parking cams, no blind spot warning in side mirrors, no automatic rear cross-traffic/pedestrian braking. I think most people assume that Teslas are ahead of other cars in technology, but IMO that's only true in powertrain efficiency and ease of road-trip charging. Like someone new to smartphones who wants an iPhone without realizing there are alternative phones with feature sets that may better suit their needs. Tesla is well behind other automakers in creature comforts and driver safety aids. I too was in the "Full Self Driving" beta, but opted back out after my car turned suddenly toward a raised median divider filled with trees and tried to accelerate into it. Any car with forward-looking LIDAR would not have made this mistake.
