Tesla's latest driving mode is an about-turn from its previous options, which were all about squeezing the optimal performance from its cars. The new "chill" setting makes for a "gentler ride," according to the manufacturer. That sounds like an odd upgrade from an EV maker that was once obsessed with cracking the fastest acceleration time, motivated by its rivalry with Faraday Future. It achieved that milestone earlier this year (after dropping the "Ludricous" easter egg), when the Tesla Model S P100D became the quickest car to 60 MPH. All those boring folk can tap chill mode for "smoother" and "more gradual" acceleration.
