Model 3 door handles as shown on the prototypes at the reveal are significantly different from Model S powered retractable handles. The 3 handles are not powered by a motor to make them come out so you can grab them. Instead you push on the wider part of the handle, at the rear of the handle, and the thinner part then moves away from the body so you can pull on it. When you release the thinner part it moves back flush to the body by a spring mechanism, some think.I recall similar threads and issues with the retractable door handles... Tesla worked that out... and now the Model 3 is slated to have them (on a mass production vehicle) and I bet the problems with them will be few and far between
