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.
Serial jump starts on a battery that is finished
A battery past its second or third UAE summer that needed one jump will need another within days, and each deep discharge weakens it further. Paying AED 150–250 per rescue several times over costs more than replacing the battery in the bay on the first visit, and it strands you somewhere worse each time.
