Actually, we are. The motor speed controllers work by "chopping" the power at high speed, and there really is significant EM produced. It almost never causes problems for PWM signals, but it definitely affects certain analog sensor measurements.

The pseudonymous poster from team 930 seemed to be warning about high power, not about EM interference, which is why I asked for clarification.
