    They do emit radiation. However, in a real-world conductor like copper wire, there are many many scattering events that interrupt the acceleration. On a macroscopic scale radiation from acceleration and decelleration due to scattering averages out and the only think you see is the magnetic field due to the current = average velocity*number of charge carriers.

    Also, electro-magnetic radiation is quantized. There will be no radiation until the moving electron has (in a very rough sense) produced enough electro-magnetic energy to "fill" one quanta.
