Standing beside the car on a highway shoulder
The instinct after a breakdown is to hover near the car, inspect the damage and wait by the driver's door. On E311 or E11 that puts you a metre from traffic passing at 120 km/h. Exit on the barrier side, get behind the barrier, and stand well back from the car so that if it is struck you are not part of the collision.
Booking a city tow truck for a desert or beach recovery
A flatbed cannot drive on sand, so the booking fails at the point where tarmac ends and you pay for a wasted callout. Stuck in dunes or on wet beach sand, book desert recovery explicitly, send a pin, describe how deep the car sits, and stop spinning the wheels while you wait.
Letting the tow decide the workshop
Agreeing mid-tow to the driver's suggested garage hands your negotiating position to a stranger with your car on his deck. Decide the destination before the truck arrives, your trusted workshop, the agency under warranty, or your own parking while you compare repair quotes, and confirm the full price to that destination in writing in the app before loading.
