If possible try not to pull out if a car is going past in the outside lane of the carriageway you want to pull into. If you are in a hurry, the somersault and roll method is a quicker way of achieving the same result, but avoid the lamp posts in the central reservation. Park alongside a yellow and black curb. If you are lucky the police will fit the car with an anti-theft device or tow it to a secure car park. There is however a standard charge for these services.
Cars travel better when on their wheels.
Honest officer, I was avoiding that pebble. And as for this one - The woman driver almost missed her turn off, instead she hit half a dozen fence posts before the car came to a rest on it's roof.
