Turn off AC a few blocks before turning off car?

And in every car I’ve ever owned I think the AC compressor circuitry includes a relay that allows the system to shut itself down when you turn the engine off, so there’s no worry about the AC compressor adding to the starter motor’s load upon starting the engine again. The compressor clutch circuitry is only enabled when the engine is running.

If the magnetic compressor clutch was not disengaged when the engine was shut off, the current of the magnetic coil draw from the battery would leave you needing jumper cables the next time you drove the car.
I’m pretty sure that that all compressor clutches need 12 volts to the clutch coil to engage the clutch.
