I had one brake lock up going over an abrupt slab transition at a bridge. According to the skid marks, the wheel lined up behind the hitch, then the brake let go. Acceleration and counter steering jackknifed me into the ditch.

Trailer manual advice is to hold steering straight and tap brakes.

Have you read your trailer manual?

Yes, you can crash a Puch and walk away. But the car was a write-off.
