Tesla claims to have built a "fully self driving" (FSD) system using custom-designed math processors, allowing its vehicles to potentially drive themselves completely autonomously.

At an all-day event at the company's Los Angeles headquarters on Monday, executives were on stage to outline the computer system, which has been installed in new Tesla cars since around last month and can be retrofitted into older models for a $7,000 fee.
