This would be due to poor shielding in lesser cables and with automotives, you have a not so great AC generator that has questionable filtering capabilites at best, with lots of RF signals from the engine, which is why shielding is all the more important. For home use, the shielding of low level lines is still important but not as much. This leads to speaker cables which are not shielded at all, well most of them, because the signal to the speakers is a higher voltage and less susceptible to interference.
