PaperBack exists. It’s branded as a joke, but it is functional!

You’re slightly off here. Elon (and Tesla as an extension) doesn’t like LiDAR, and doesn’t use it in any of the vehicles. Cost, complexity, and sensor fusion issues make it undesirable to them.

Tesla is using a vision only approach for their various driver assistance features, including FSD (and you should be able to find presentations where he mentions that humans use vision, so the cars should too). Whether that is a good thing or not is up to interpretation.

None of the past or current Tesla models have LiDAR sensors - only radar, ultrasonic, and 7/8 cameras (with radar and ultrasonic sensors being absent from some newer vehicles)
