Guille G. Alfonsín described the presentation of the Tesla Roadster as a very effective advertising maneuver to showcase the company's technical capabilities and attract attention, although he noted that the vehicle presented did not match the 2+2 convertible electric sports car reserved by customers in 2017. According to what he wrote, the model had initially been promised for 2020 and, nine years later, Tesla announced another two years of waiting. Alfonsín highlighted the engineering of the demonstration but warned that marketing a vehicle capable of controlled flight would require aeronautical certifications and operating authorizations, in addition to road homologation. He also raised doubts about the use on open roads of fans that generate aerodynamic lift by sucking air underneath the vehicle, due to the risk of expelling dust, gravel, and stones at other users. The engineer considered the demonstration technically notable, but questioned the commercial value of the product and the delay for those who had reserved the car. He stated that Elon Musk continued to make promises and delivered only a part of what was announced. Alfonsín said he would analyze the technical aspects in the PowerArt videocast and in upcoming videos. #Tesla #Roadster #Ingeniería (translated)
