They deceptively claimed that for additional money the customers' cars would be enhanced in the future with FSD. They then made that claim again each time they failed to deliver. They continue to make this claim and people are trusting it.
A lie hides the truth.
But they lied a lot though, right? "Cross county automous summon in 2017" "Coast to coast autonomous drive in 2018" "Tesla driverless taxis in 2019" are a few examples. One may hold the view that Elon musk can make grandiose statements about solving AGI and nuclear fusion in 1 hour and make futuristic statements about that, but when does it go from projection to lying?
