Is it better to blast my car A/C and then turn it off, or let it run at a higher temperature continuously?

In terms of energy usage, which is more efficient?  Say I turned the temperature on my car A/C all the way to its lowest setting and blasted it until it was chilly, then turned it off, and repeated this. Would that be more or less efficient than leaving it at a higher (but comfortable) temperature and letting it run continuously?

Car air conditioners have one temperature setting; only the fan speed changes. The most efficient way to cool down your car is to turn the fan up (the difference in energy consumption between speeds is negligible in the short term) and recirculate the air in the cabin.
