Youtuber Goodwinb99 recently uploaded some video from inside his Tesla Roadster while driving in the snow.
The Roadster is fitted with 'winter' tires but it is still a great demonstration of the Tesla's traction control in action.
The effectiveness of the T/C is put into perspective when at 3:40 it is tuned off for a brief moment. The electric super car simply spins it's wheels up to highway speeds while at a virtual stand still.
With T/C on the driver can literally floor the throttle while the electronics figure out how much traction is available.
