I've uploaded the video to youtube to show you guys. Near the end of the video, when I start accelerating, you can hear how it doesn't accelerate smoothly and the fast I go, the worse it becomes, until it refuses to accelerate anymore.

The specific part is 0:24 to the end. The times before that were me letting go of the gas because I was scared to drop my new phone.
