First, I didn’t say it came to a dead stop before it dropped. I think the impalement killed its momentum. Second, fast probably wasn’t the right word, but she hit the gas hard enough to climb that bollard. I was thinking she just plowed into it, but she might’ve backed into it slowly, got stopped, didn’t know why, then pressed down harder on the gas. That would explain the minimal impact.

My guess is it wasn't speed. It's probably an all-wheel drive car and the front wheels are really close to the front.

So a stubborn driver could tap the bollard, get mad their car stopped, then after contact hit the gas hard and ride up the bollard while still keeping traction on the front wheels because they're never pushed off the ground. The bumper would take less damage because after the first push most of the motion is upward.
