You should be a god in RC cars handling to do it.
This video was filmed in Yokogama, Japan at the WARU Circuit, where locals improve their skills in driving small cars. Sounds childish? Believe me, you need to have very strong spatial intelligence and instant response to perform such stunts with a remote controller in your hands.
Also our respect to the team of Kuma Films who filmed this race of RC drift cars!
How did they film it? Watch behind the scenes:
