Human Factors
I was in pattern and announcing position. ADSB [Automatic Dependent Surveillance Broadcast] showed approaching aircraft at same altitude and less than 1 mile coming toward me while I was on final. Bonanza; easy to [identify] that close; did not announce down wind; base; [and] final. I asked on UNICOM if he saw me as he was turning toward me (his base turn)...he replied yes and veered behind me. I extended my landing to over 1/3 down runway with no idea where he was. He did not say anything more after acknowledging my question. As we rolled off runway to taxi to terminal; he was less than 100 feet behind me. He had landed behind me! I tried to speak with him but he had macho attitude and said it was my fault...I spoke with FBO; they had UNICOM radio on; they confirmed he did not announce downwind; base or final.
Mooney pilot reported while on final approach; another aircraft followed closely behind and landed within 100 feet behind him.
