A driver who was filmed inhaling laughing gas behind the wheel before a 100mph (160km/h) crash has admitted killing three teenage friends.
Thomas Johnson was speeding when his car hit a tree in the village of Marcham, Oxfordshire, killing friends Ethan Goddard and Daniel Hancock, both 18, and Elliot Pullen, 17.
Johnson, 19, admitted three counts of causing death by dangerous driving and is being sentenced at Oxford Crown Court.
The victims' families called him a "cocky teenage boy" who was showing off and urged others "not to be that driver who shows such disregard for their friends' lives".
