They're accomplished by having the more powerful front brakes hold the car while the less powerful rear brakes allow the rear wheels to spin. Sometimes water is used to reduce traction. Sometimes the brakes are modified so that the front axle can be controlled by a hand lever without applying the rear brakes. In this case the Tesla was able to overpower its more powerful brakes and drag the car forward. That should never happen.
