Here's a video
Hold until the boost meter is empty.
Rinse and repeat 10 times and the trophy is yours
While in a match, drive over the boost powerups to fill your boost meter. The powerups on the edges of the arena fill your meter 100%. Once your meter is full, press and hold to empty your boost. Repeat nine more times to unlock the achievement.
This is very easily done in Exhibition with bots turned off. Empty your boost without touching any orange objects around the map. Then, touch one of the pads with an orange orb floating above it:
Then, hold and completely empty the meter. This will launch you most of the length of the pitch, so be sure to avoid other orange pads. Repeat the above steps 9 more times. The trophy will unlock as soon as you deplete the meter for the 10th time.
We just roll around the map, use the booster, accumulate and use it again)
You won’t even notice how the trophy will fall out.
