Last year Chiptole launched a game to win a Tesla. No winner was ever announced
The racing game was mainly one of endurance, the longer a player could last without crashing, the greater their chances of getting higher score. It didn't take long for some players to write scripts to keep their car going for hours, automatically detecting obstacles and switching lanes. Nowhere in the contest rules was this or any kind of scripted play explicitly forbidden.
Despite this, the contest period came and went, and Chipotle has never made an official announcement on any winners for the top 10 prizes, including the Model 3.
Several media outlets reported on the contest when it was launched. Apparently none of them followed up on the winners.
