Tesla turns your smartphone and an app into a key fob on steroids. There’s no need to think about unlocking doors or pushing a start button. Step on the brake pedal and the car is ready to roll. After reaching your destination, simply put the Model 3 in Park and leave. The smart tech knows when you walk away. It automatically turns the car off and locks the doors. It’s brilliant. Tesla manages to eliminate unnecessary steps to create an experience that feels lighter and easier than a traditional vehicle.
