I wasn’t expecting to get one of them. Wasn’t even sure a normal one would be possible. I got one basic one when attempting.
I got it after an Ozzell-level failure to climb a ramp to get more speed using a bit of gravitational potential energy. An embarrassing miss ensued; tried the climb too near the edge with a wheel missing the ramp entirely. Really, really amusingly awful of me.
What it did do was this. The car fell off the ramp and nearly turned over. Didn’t quite and put the “car” into a doughnut (ie, not rotating on-the-spot) with the wheels spinning and the I saw great . . . awesome . . . ultimate.
So, yeah, unexpected.
