I’ve had the Model S for two and a half years now, and it has about 39,000 miles on the odometer. It’s a 2016 90D with the first-generation sensor set and 19-inch wheels.

Somebody asked whether it’s a good idea to encrypt database columns in a web application. My answer: “It probably won’t help much.” Why? Figure out your threat model Best practice: figure out your threat model before you spend time and money securing your system.
