I feel like some of the frontier models are approaching run-of-the-mill engineer who does dumb stuff frequently. That said, with appropriate harnessing, it’s more like go-karts on a track; you can’t keep them out of the wall, but you can reset them and get them back on a path (when needed). Not every kart ends up in the wall, but all of them want to go fast, so the better defined the track is the more likely the karts will find a finish line. Certainly more likely than if you just stuck them in a field with no finish line and said “go!”.
