Tom and Ray never reply to anything on here, so that hope will not be answered.
Generally, warped rotors will only produce symptoms when the brakes are applied. They will present a shake, pulsation, or shimmy in the steering wheel when braking for front rotors, or in the seat for rear rotors. If you have this vibration whether you are on the brakes or not, it could be something else, like a bad tire or a wheel out of balance. Has your mechanic done a runout test to verify it is rotor warp?
