Had a friend look round our HSE Dynamic today...
- he wondered what safety features were built into the car to ensure that the tow-bar didn't retract with something attached to it (say if the kids were in the boot and pushed a button)....

Well, he stood on the tow bar, i hit the button.... and yeah - it retracted.

Small risk of that happening in the real world, but imagin the damage of hauling a cycle carrier through the bumper. 2022 P440e AB
