I do this as well.
A modern A/C will cycle. It does that naturally, however it dosen't cycle based on the temperature you set in the cabin as far as i know. Rather it cycles based on the pressures the A/C system sees. If your driving on the highway, and don't have a grill block however, the highside pressure won't get high enough to tell the compressor to take a break I don't think. This isn't something that gets tested in the EPA test, therefore there is little incentive to have a smart A/C. However, many A/C's will cycle off during heavy aceleration.
What would be damned cool would be a 2-stage compressor. 1 for light cooling needs, 1 for texas.
